Well i went through with the th-350 swap to the firebird, everything went suprisingly smooth, now i jsut need a driveshaft. The 350 has the 6" tailshaft, so my shaft ends up 3 inches short, I was given a list of cars that were equipped with th-200r's, which should have the shaft i need, but after a day at the autowreckers I still have no luck. The th-200r is the same length as a th-350, so a 3rd gen camaro or firebird with a th-200r4 would be what i need? I was told soem in 82 and 83 had them, anybody got an answer or suggestion? I really cant go and spent 200-300$ on top of all this to get one made, thanks guys.
