I just installed a th350 with a short tail shaft in my 82 Z, I am going to need a driveshaft and was wondering if anyone knew if I could use any GM car that had the same set-up and use that driveshaft. If the length is the only consideration then it should work...right? Thanks

You should be able to use the stock driveshaft if the car had the 3 speed th200 in it.

^^Yep what he said. I used a DS out of a 82 Z28 auto for my short shaft TH350 swap.

Mark.
