May as well throw this out there while I'm redesigning the Trick-6 suspension.
225" Buick V6 engine and T5 five speed OD trans.
The original real diff was taken before I got the car and would never work anyway.
Original rear leaf spring is gone and not missed, expecting to use coil-overs.
Being a +/Mk. III it had the roto-flex couplings.
I need to create an entirely new rear suspension.
Thinking of using Merkur XR4TI as it's fairly available and has the correct 4x108 PCD for my 14"x6" Enkei wheels.
Anyone ever fit the Merkur/Sierra rear to a GT6?
It's about 8" too wide in stock form.
Would also want to upgrade it to rear disc brakes.
Scrap everything from the original rear, or just the diff and axles?
Would like to keep as much as possible "Off the shelf".
I see lots of post on using Subaru diff's, why not the Ford?
I can also readily get Ford T-bird 8.8" diff's but they are pretty large and more than I need for a V6.
