will not sit well with your current steering box setup (unless you have an '83 which most had rack and pinion steering)
So, other things to add to your list: AE86 or '83 "AE" chassis crossmember
(rack/pinion version) or weld some tabs onto your existing member AE86 Steering column or from the '83
Mk3 Supra steering joint
AW11 manual steering rack
Two more things:
1. keep your eye out for some FC RX7 4 piston calipers
at the J-yard and get the bracket to mount them and mini cooper rotors from a member on Club4ag,
2. I wouldnt waste the money or time on finding the Mk1 supra rear end- Solution: Ford Explorer 8.8" rear end
- you will have to have to driver side narrowed to match the width of the passenger, then you can get another passenger side axle and use it. A lot of the 8.8" come with LSD's already,good gear selections stock (3.73 or 4.10)
I purchased my 99 Explorer 3.73 LSD rear end @ Pick N Pull on Thanksgiving morning 50% off with the spare axle for just over $75 and our local rear end shop quoted $150 to narrow the axle and another $200 to remove and add the TE72 suspension mounting brackets.
Then add a C-clip eliminator kit, maybe a girdled diff. cover and you have a bulletproof rear end for about what your going to spend on the stock supra rear, give or take.
Let me know if you have any questions, I have put countless hours researching this swap for my TE72. Also, early model Tundra/Sequoia headers work with a little change to the collector position (pics of this to come
