After much deliberation I made simple reinforcements for the traction bar mount out of plate. Used the same radius edge design as the next forward plates, which fits well around the cab mount cross member. Same bracing on other side.
Hopefully that's it for frame mods. Trying to decide if rear bump stops need additional support.

|350TacoZilla||Is there enough hose on shocks to put the reservoirs on the tube crossmember you made, maybe driver side one on passenger side and pass side on driver side? Just thinking they would be up out of harms way more and could still use the mounts you have if tube diameter is same as shock bodies.|
|03-27-2020 11:22 AM|
Not sure I needed to, but I made some reinforcement plates for the rear shock mounts. The tube ties into the vertical part of the frame but not much.
Made a simple shape out of 3/16"

Decided on a plan for the traction bar forward mount. Went with the lower 2" bar below the shackle, so just a main cross bar was needed above. To clear driveshaft it needed to be up quite high, I again used the slice method to attach. Tube is some leftovers I found, 1-5/8 OD, 0.225 wall DOM.
Since chassis is light it sits up 4" higher than planned ride height. This impacts the geometry, so some compensation is needed to build at a different height. I set shackle angle to be vertical at ride. Started to tie the cross bar into the left radius arm mount, but put that on pause for now. The traction bar will only apply a vertical load, however it will want to lift the whole chassis at bar attachment point. Plan to add some type of reinforcement.
Fit, welded, painted and installed the links. Also cleaned the center section of the frame including the only 2 remaining factory cross members. Didn't fill any more holes, for now.
The lower link is 60" which is right about what driveshaft will be. Angle is similar, will keep pinion pointed at TC at all times. It seems to hang low, but driveshaft will be right there too.
Installed the rear shocks.
Put the reservoirs on the shock bodies for now.
The published compressed dimension of the 12" travel shock didn't include the 'bumper'. So effective travel is under 11.5", and at 12" horizontal offset yields a little over 13" of vertical travel. Bump stop will limit up travel to prevent shock from bottoming out.

I started to make templates to box and then my engineering brain wanted to justify the weight gain for the improvement in strength. Many of the areas didn't provide much gain, so I reconsidered. Boxing also makes running the plumbing more of a hassle.
It was box the whole thing or only as needed. I chose 'as needed' with goal of not further degrading frame integrity. If full box, might was well just make a new frame out of rec tube. For my intended use boxing isn't really necessary, and I'm trying to keep it looking like an old truck.
|03-23-2020 09:19 AM|
Man, attention to detail is phenomenal. Loving this build.
Why no boxed frame tho?? Had to ask
|03-20-2020 01:02 PM|
Got the diff hacked up and brackets installed.
Moved the perches for -1 pinion angle and welded up the shock brackets. Threw some paint on it and re-installed the axle. I positioned the brackets such that nothing hangs below the tube. Everything should fit...
Went forward with traction bar links. Welded on the bushing sleeves and test fit to see what to do with the frame end.

It's hard not to go extra overkill, but most often that just pushes out time frame to get behind the wheel. I want to drive/break/fix this thing at some point.
Ya, big is fill vent, the 3rd little line is a vent/charcoal canister. Probably just vent to atmosphere.

progress is looking good as always
nothing wrong with a good set of leaf springs, for what you are building i think linking it would have been a waste of time and money. plus like you said it would be a shame to cut the box up.
looking at the chevy fuel tank and pump set up and im liking it for an upcoming build i got planned. the 2 other lines on the sender are for what? im guessing the larger one is a vent line, but what is the smaller one next to the feed/return lines?
|03-19-2020 11:25 AM|
Burned in the shock mount bar and was forced to miter and cap the ends, well because.
I guess I have to paint each step so it feels like progress is made. Or something like that.
Tacked the lower shock mounts onto the axle such that they do not go below the axle tube. Angled them (and uppers) in so the shock end bearing are almost straight at ride height.
Pulled the assembly to make it easier to work on. Have to re-clock the spring perches, weld up the shock mounts, and get the trac bar brackets on.
Even on a full size rig space is tight between the diff, trac bar, shock, brake line and so on. Plan to cut some of the diff housing off to keep the bracket in the shown location. This will allow me to weld the inside of the inner bracket to the tube itself.
So at this point the smart people are wondering why I didn't' just link the rear. Before buying the leaves and making the hangers I considered but did not for the following reasons;
- The leaves will perform well enough for my application
- Link kits are over $1000 not including truss, springs/coilovers and so on.
- Don't want to hack up the bed for a good coil over mount geometry.
- Didn't want to go to the cost and effort to link and use regular coils, although air bags would be a decent option. Then I would need a air system and so on.

Semi-committed to rear shock frame mount scheme. Made a measurement/math error on horizontal part of the shock dimension and ended up ordering a 12" travel shock for a 30* installed angle. The bed cross rail is right in the way of the area where frame is bent to clear. Ended up putting the mount in front of the bed rail which ended up being the right distance anyhow so it all worked out. Since the bar needed to be up high I sliced it like the engine cross member which gives lots of weld area. Ground out the tabs to mount at a slight angle and positioned to clear the reservoir hoses. Plan to mount both reservoirs on the cross bar

Getting fuel tank mounted. Used some cardboard to space and locate tank and upper stops. Plan to use some 1/4" rubber to isolate tank from frame. Mounted the upper pieces at an angle to center and prevent a pressure point on tank.
Used the press to bend a pair of tabs for the rear mount. Simple mount now that the tube was relocated.
Also used the press to make some angled brackets for the front. Bent both legs at an angle to get the center perpendicular to the tank strap studs.

What's up with that oil pan wall art/ tool holder?
|03-10-2020 09:49 AM|
My 77 bronco had only a 14 gallon tank and I never ran out of fuel, even getting 10 mpg. So twice that plus clearing the diff seemed like the best option.

Got some work done on the chassis around the fuel tank. After getting the actual tank in place, I decided to go ahead and remove the 2nd rear factory cross member and build another out of 2x4 3/16 wall rec tube. I debated actual location and ended up putting it forward about 3" of the original, about where the lower frame bends start to prevent a decent attachment point. The tank hangs down enough to hit diff, and the location provides about 2" of horizontal clearance at bump. There is wiring on the left side so I made provisions with some 2" tubing.
Then I accepted that the rear most cross member was not in the ideal location and carefully cut it out so it could be moved forward about 4". This solved a few issues, reduces weight and will simplify tank mounting.
The rear most bed bolts were blocked and accidentally welded shut, so I re-drilled them and can use typical bed bolt.
I had drilled some mounting holes for the bumper/hitch, but a few now interfered with the wiring pass-thru, so moved them. This area will get boxed so captive nuts were welded in.
Moving the cross member closer to the rear hangers helps reduce flex, so I did minimal boxing between the two wih 3/16 plate. cut a vent so dirt and crap can't get trapped in it. I think the rear part of chassis is at least as strong and rigid as it was. Had to paint the frame as I went to make it feel like progress was being made, as opposed to just re-doing stuff.
I wasted a lot of time filling pretty much every hole in the rear end of the frame. Should make the wheel well look better. For some reason I feel compelled to fill holes from the items I have removed.
At this point I think the 40g tank could be made to fit but would need longer bump stops to prevent diff contact, ultimately reducing up travel. So the 31g fits nice and should give 250-300 mile range.
Next step is provisions for tank mounts and straps. Plan to mimic the blazer/burb mounting system with some flat bar welded to the rec tube, and some mounts for the tank strap studs. Moving the rear tube made this easier and will match the other end. The forward tube provides a nice place to put the fuel filter.

I guess I don't really care which side the fuel fill is on. Half of my Fords have on the right.
I did end up moving it forward as far as it made sense, for the reasons you stated.

Got the 31g burb tank test fit. the dimensions are from pinch welds and not the tank walls, so smaller than I thought. the 40 gallon would have just fit. No need to narrow frame rails, so that is good.
Big ass tank hangs way down as expected. will need a cage or custom skid plate of some type.

Trying to decide on rear pinion angle to mount lower shock and link brackets. Called Tom Woods and they said go double cardan if u-joint angle is over 9*. Took some measurements and did the math. I'm at 9-10* at ride and it goes up from there at droop. So I think I will go with 1350 double cardan front and rear. Bringing pinion up to 0* at joint also lowers driveshaft angle itself.
The traction bar is just a radius arm anyhow, so it is a good fit to the double cardan configuration. Traction bar will keep pinion pointed at transfer case at all times which is what shaft needs. Both will be similar length and angle.
I fucked up my shock calculations and will have to get creative to get the 12" shocks to fit. The bed cross support is right in the way. Got some 1.75 x 0.165 wall DOM for the mounting.
Might need a small body lift to make trans/TC fit under cab, but trying to make shocks and fuel tank fit under bed without additional space.
