I too have that kit, its a custom built rear end so to find one would be hard, I have a ? for you, what do you ask for if you need brake shoes. what year car uses 7 1/2 ford rear ends.

You could get any 7 1/2" for rear and the swap out the ring & pinion assembly. You will still have to re-shim the differential due to the thrust being backwards due to it being upside down/backwards.You'll have to reuse the shortened axles and the axle housing you now have is all.

 

As to the drum brakes , while they did the job I've never been happy with their stopping power, especialy when I pulled my trailer, so last fall I swapped them out for discs. I used a set off a 96 Ford Crown Victoria. It had the correct axle bolt pattern and the backing plate slipped perfectly over the axle tube. The mounting holes were slightly off but by re-drilling they mounted up tight. I also had to replace the rear master cylinder as the stock one didn't push enough volume to properly expand the pistons. I did find that early Mustang rear discs would work, probably better, but weren't cost effective. Salvage yards thought they were made of gold.

Now the brakes are excellent.

Look for an early 70's Ford Pinto they used a 7 1/2. If my memory serves me some of the 70's Ford mustang II's also had a 7 1/2. Junk Yard maybe, very popular rear end for dirt track racing out this way and getting hard to find in good shape. Good luck

Call randys ring and pinion. I use them all the time for rears.

Contact MotorTrike in Texas - I believe they use the 7 1/2 rear end and it's a ford.

Just replaced all the brake shoes/hardware on my RSMV/Tri-Wing trike this morning...All the parts were 1974/75 Pinto or Mustang.........Would think the differential would be the same....Just a thought....Bob D

I just bought a 2008 Tri-Wing Trike with only 2,800 miles on it.

I am not happy with the brakes either. What master cylinder did you use to replace the stock one?

Also Does anyone know where I can get a cover to fit just behind

the stock side cover?

Sorry didn't see this post earlier. Anyhow I used the following master cylinder kit ( http://www.jegs.com/i/Wilwood/950/260-5920/10002/-1 ) as the stock master cylinder didn't move enough fluid volume to properly expand the large calipers from the Ford Crown Victoria I used.

There isn't any covers available for that area you speak of. I welded in sheet metal to the angled 1" support bar. It was cut out to follow the curved frame. I also welded in sheet metal to the kits side mounting plate to close off that area too.

You'll find a 7½" rear in BroncoII, and Ranger pickup, with a 5x4.5 bolt pattern. The majority of the Mustangs with 7½ are 4 lug, and the 5 lug are 8.8 axles. Considerably heavier. What parts do you need? I just threw away a ring and pinion yesterday for one, it is a 3.54 ratio. I can retrieve it until next Friday if you want it.

I don't know what the Tri King is using, but if it is a 7.5 ford I would bet the insides are stock ( bullet proof ) parts, and available at any auto parts. The big rub is they ask for year before any thing else,,,. The Hannigan uses a Thunder bird rear mounted upside down once again unknown year range. Easy to change out the gears, and seals ( messy as hell, but not that bad of a job )
