What if i replace the output shaft with a long corvette shaft ? I also got the rear cover . will this work with the rear prop ? Im building a rear drive race car with GB tranny here
Make sure you cryo the long shaft. It'll stress relieve it very well. No nitriding. That'll take out the "give/twist" that longer shaft needs. Nitriding will usually done about .010" deep.
I forgot to tell you, make sure when the suspension binds up in the back that it won't shove the driveshaft forward enough that it will "bottom out" in the trans. That's how the shop across town from me went through a ton of bellhousings.
