Ok,Heres the deal.I bought 44x18.5x16.5 TSL swampers.To go on my 78 bronco.The bronc has 4'' lift.And i cut the wheel openings.With the tires turned to full l/r.They hit the front cab mounts.Don't want to lift it anymore than it is know.Just wondering if anybody has a fix for this.Like relocating mount or modifying(sp) it.
TIA

To really fix, you're either moving the axle forward or the cab back. I know, been there - done that. However, you can gain a little between now and then by building a plate mount that goes over the top of the existing frame mount bracket & then cutting out the stock bracket. Will gain you about 2" clearance and eliminate that sharp inverted cup that the stock mount has. BTW, the stock mounts will cut blocks of tread off 37" Swampers when you jump hard...just a little tidbit. I'll try to post some pics of the way I modded it.

loveshackle,Could ya post a pic of your setup please?

TIA
Tim

Sorry. Couldn't get decent pics to show it in a helpful way, then I forgot.:confused: Working on another '79 F150 at the moment (down to frame with back end chopped off for 4-link) & will take some pics & do a cheap photochop. Other rig is out hunting & it's really hard to see, other than the bucket being cut.

Cool Thank ya

Okay, here ya go. I apologize in advance for my shi##y photochop abilities, but I hope you can get the idea.

Picture 1 --is the stock unit with obvious rub area. This is from the CENTER tread blocks on my 37" TSL Radials. With 3" backspacing wheels, I thought it interesting that the side tread didn't hit, but the center did.


Picture 2 -- On the first truck, I just unbolted the front mounts (yeah, like it was that simple after 27 years), jacked the front of the cab as far as possible (5" was sufficient), and plated the top of the mount with 3/16" flat stock. Basically, three pieces (red, black, blue) welded together & to existing bracket. I then cut out the offending area (yellow). It has held up fine for about a year so far.

Here's where my pics get crappy. Hope you can decipher.

These are the mounts I 'would' build for this truck, if I weren't moving the front axle forward ~6".

Picture 1 -- After stock mount is removed & frame is sandblasted. Plate 1 (3/16") is welded (edges & 2 plugs) to stock frame with small overage on outside edge of frame.

Picture 2 -- 3/16" plate (Plate 2) welded to side of frame (approx 5" wide x frame height) & to Plate 1.

Picture 3 -- 1/4" plate (Plate 3) is tacked in place at height of original mount hole on a horizontal plane. Perimeter of mount hole is 3/4" due to greater thickness of plate. Despite my image, plate is 1.5" wider at frame end than at mount end.

Picture 4 -- With top length determined by actual rubber mount used, Plate 4 (1/4") is tacked in. It is centered in Plate 2 (front / back) and is a triangle, with the corners being A) bottom center of Plate 3, B) bottom center of Plate 2, C) Center of inside edge of bushing under mount hole in Plate 3.

At this point, these plates are welded in place, vice the front & back corners where Plate 2 & 3 meet.

That is the main structure. To finish it up, I would run a long Plate 5 that mimics Plate 4, but longer on top, along the back side of the mount. (Picture 1). Do the same on the front, but the same size as Plate 3. (Picture 2). These plates are 3/16".

Now box them underneath with 3/16".

Done. In comparison to the stock mount, you have eliminated all the black area in Picture 3.

Sweet. I went ahead and cut the hole mount off.Fabed up new ones with
1/4'' plate and 3/8'' plate.All that work.And only gained about 2'' or so.
Thanks loveshakle for your time.Nice photo chop too.

Glad it worked out. Not much you can really gain with the stock axle position & the pretty much permanent cab mount location. That steel may be overkill, but I planned the above based on the '76 F250 Crew Cab fully loaded with toys that I'm using. Like to see some pics of your project sometime. Take care & Ho Ho Ho.
