TH-350 Tailstock swap!!!!
« on: March 20, 2017, 04:27:30 PM »
Hello!!

I have an 84 C1500 with a 355 and a TH-350 with a 9" tailstock and a stock converter.  I am making this truck into a little street/strip project, and a buddy of mine has a freshly rebuilt TH-350 with a shift kit and stall converter in it for DIRT cheap! BUT it has a shorter tailstock!! Am I pooched OR can I just simply swap the tailstocks or am I basically have to completely rebuild the tranny?

Any info or insight would be GREATLY APPRECIATED!!!

Thank you!

The tailshaft housing correlates to the output shaft length. It would be cheaper to have your driveshaft resized.

Just change the driveshaft and move the transmission crossmember. 

Pretty easy to do.
