Thanks guys. The reason that I'm going to be able to run these angles is, I'm running a 2-piece front DS. The front section(or midship) that runs from the T-case to the Center support bearing, will be really short. It will have a 1350 at the 205 and a 1410 at the bearing, the whole length of the midship will be less than 10" probably closer to 8.5". This will allow me to split that angle to two joints. The T-case joint will be running constantly at an angle pointed down. Then I can use the high misalignment of the 1410 for both ends of the long shaft with the slip in it. I already set up my front to point up (the pinion) as it goes down (droops out). And as long as I can have that 1350 be happy at the T-case I think that I'm going to be OK. Remember at full droop my pinion will be pointed up and my midship DS will be pointed down.

damn dude... you've been busy... looking good ... I party my house monday..

if you do replace the s10 fan the hhr electric fan is about $60 at rockauto and has been known to keep 460's cool.

love what you have done with the dodge and the chebuggy. glad you did a build thread for the rebuild.

wanna buy a 205 output yolk? got one that will fit great. Will sell it to you for space to keep my new slide in

Pics of the Blazer with the front at 18" droop, from full stuff. And a before and after of my old axle that is going to a new home, after it gets checked out and straightened (if needed). I also got my Front DS to clear and spin freely at 18" of travel. I think it has a bit more so I think that I will not have a problem running 19" of front and rear travel.

[K5runner@hotmail.com]

Ok so let me explain how the drive shaft is working. I posted a pic of a sketch but I will go into detail. At full droop the pinion is pointed up at about 10*, while having about 2* of caster. Which is fine because the way my links are, it just gets more. I think it gets to about 10* at ride height. The T-case points up at about 6*. So what I did is made a midship shaft of 11". Made that -6* into a 12*, so now my midship points down at 12*. Yes it got shorter but more importantly the angles now all point to each other. Buy doing that I have 18* at the T-case 23* in the middle and 25* at the axle. Now the T-case will always be at the 18* which is fine (I think), but the rest will just get better. I will have to fab a mount for the midship bearing but I will do that later. I now know that the DS will work so I can get back to worken on my tubing. Oh my old DS was 38" with a 1350 CV and a 1350 at the axle. Now I have a 1350 at the T-case and 1410's in the middle and at the axle, with an 11' midship shaft and a 27" front section.

Oh I should also be getting my radiator back soon, it's being redone. They are making a fan shroud and mounts, the fan shroud will hold two taurus fans. I'll post some pics as soon as I get it. I'm having it made because I do not own a TIG, nor am I good at TIGing. So I will gladly pay the professionals to do the work that I cannot. Plus TIG welds just look cool and I need some on my Blazer.

thanks for the pm

here are some more specs and a part # for the hhr fan. it has measurement and outputs for the taurus fan and the markiiiv fan as well. this is from a build for a ranger with a 460 in it.

hope it helps.

I've got to quit staring at your pictures of the frame modifications and panhard rod mounting. My truck isn't close to rolling under its own power, and you have me wanting to redo my panhard rod setup already.

Thanks a lot...it's not like I didn't already have too much other stuff to do...

[K5runner@hotmail.com]

Okay so a little more progress over the long weekend. Now I'm scratching my head trying to figure out where/how I'm going to mount the petals. And if I'm going to build or reuse the stock clutch petal. I do have a few idea's running threw my head though.

[K5runner@hotmail.com]

You can see in the background my new truck. Its a rust brown pile of shit that has no motor trans or t-case, it has a SF 9.5" 14b in the rear and a 8-lug 10 bolt in the front. But it's a 1975' so that means NO SMOG. It's going to sit for a while.

[K5runner@hotmail.com]

And a couple more of the shock mount and the area I have for the bumps to go into. On top of the link mount.

[K5runner@hotmail.com]

BTW those are SKY high steer arms with 9/16" ARP studs with lugnuts and a 1" set screw for the load bolt.

A 75 cab on a later chassis or an axle swap was performed. Should have had a 14 bolt FF and an external hub 44 front. I know it won't matter much down the road. The Blazer (or what is left of it) is looking good, gonna be pretty nice when finished.

Ya there just rollers, no axle shafts on front or a tie rod. but it has some of the early 36" mil tires on the back with some 33's on front. I believe its the original chassis.

I found the VIN stamping on my Blazer (on accident) I wonder if the trucks has it in the same spot? It was on top of the frame on the pass side just behind the shackle mount for the front springs (passenger feet area). Kind of pain if you had to prove it to the CHP. Would they want to remove the cab to see or ????

One question I had: If I remove the cab and replace it with a different one (Toyota for example) and kept a Chevy drivetrain. So the only thing not from the original truck was the cab, can I still register it as a 75' Chevy?

[glenns89]

I believe you can register it as a special vehicle. I remember hearing an S10 on a different frame that had a special reg that didn't have smog.

Looks good, I really like the stub shaft idea. I hope you plan on gusseting or plating that lower link, that shock will eventually bend that and or wear that heim out.

Promise us you will get a video of this monster in the whoops I wanna see you pass a rail with this pig!

No plans on any gussets or plating. It's 2"x.25"wall tubing with the shock mounted to the end. If I need to I would put a bend in it (bent up)and gusset/plate the bottom. I'm just going to leave it the way it is for the time being and keep working. Too much other stuff on my mind.

That's for sure. I need to get video for shock tuning also.

I cannot wait, I'm hoping to be able to take it out for Turkey day at Glamis.

[just4cuz]

I thought the trucks had the vin on the drivers side frame rail, not sure though.
The DMV website has the explainaton under the "How to register a custom or antique vehicle in California".

Antique has to be 39 years old or older (1972)
Custom vehicle requirements looks like it would be easier to keep it a 1975 some how.

[K5runner@hotmail.com]

Okay so I got a little more work done. Still no camera but I hope to get it tomorrow. I put a tube that goes over the motor, right in front of the throttle body, for more support. I got the front tube section welded up and started on the upper shock mounts. I think that I can finish the shock mounts on Mon evening and hopefully on Tues begin to cycle everything. I hope everything goes together well. Then its on to the radiator mounts, I think I should be able to get my radiator tomorrow. After the radiator mounts its the firewall and dash. I always wanted a dash on this truck.


What I' thinking about now (trying to stay ahead so that I don't have to wait for parts) is the brakes. I want to run a turning brake, like the one on the buggies. But since I have a Detroit and may end up with a spool back there, is there a point on a twin lever? I think that a single lever single action will be fine. What do you guys think? I already have a ball valve that's rated for a ridiculous amount of psi, something like 20,000psi of steam, gas, water, oil, etc. That I will be using for an E-brake. Got to love McMaster-Carr.

Okay, so I had to redo the shock mounts, lower and upper. The axle moves left to right too much to use the lower links as shock mounts. The shocks are going to be mounted to the axle and I have to figure out where the bumps will go. Probably on top of the truss.

I have it all mocked up and cycled everything finally clears. But I'm down to about 17" of up and down travel. But more importantly at full stuff F/R are about level. I was told that that would help with shock tuning.

I got the wilwood petals tacked in, and need to start the clutch petal. I decided to keep it as a manual system. So I will be making a linkage to connect everything.

I got my radiator home on Tues, but just got back in town yesterday. Man this radiator looks I'm going to be running 2 Taurus fans, on a 4" core radiator, a Nascar take off. I had a new shroud build as well as a cradle for the fans, new 1.5" upper hose barb and a new 1.75" lower hose barb. There longer to stick through the shroud. He also added a billet cap fitting and mounts.

So I will take a bunch of pics and post up my progress. I should be able to crack down on it all weekend long.

[GMCTruxrule]

man I love the shit you do to this rig.

I wish I had a place to work on mine...........

[K5runner@hotmail.com]

Now for some pics
A few of the newly redone radiator.

Special thanks to Richard from Atomic in San Diego.


And yes, I'm running 2 Taurus fans

[K5runner@hotmail.com]

A few of the Wilwood petal mount, that's still going to get some more work done to it. Cause I still have to figure out clutch petal and mount the orbital valve.

[K5runner@hotmail.com]

The (new) shock mounts.
