I'm looking to buy a complete rear to convert my 83 Celica GTS to 4 wheel disk and gain the 7.5 rear diff. If anyone has a rusty parts car kicking around let me know, I'd like to keep my IRS in the process so IRS cars only please.
If your car is a GTS, it will already have rear disc brakes. You will need a 7.5" pumpkin and the 2 CV shafts, as I believe the ones for the 6.7 are a different inner bolt pattern but I could be wrong. You can check as the 7.5 CV shafts have the same size of 4 bolt pattern on the inner and outer.
