I am doing a 350 swap in my 87 turbo 2 and i am having trouble find out info on the driveshaft and diff. I plan on using a T-5 trans and i wonder what driveshaft i need to make in work with the stock rx7 rear diff.

Thanks

 

custom

 

A t-5 trans will have the shifter much farther forward than a T-56 and approximately just below the radio/ashtray. You may want to reconsider the T-56 which is very near the stock shifter location.

Driveshaft for a T-56 "can" be a C-4 corvette aluminum shaft or a custom one. Custom shafts are only ~$400 so not that big of an expense.
