Does anyone know the lenght for a th400 to a stock rear end. Also what the specs would be if I have a u joint for a ford 9". The that's where the drive shaft was connected to. A ford 9". So I need to redo the u joint to a 10 bolt rear. Does anyone know? I'm clueless bout the u joint.

 

I just did my 400 turbo converison, and have the stock rear for now. I got a yoke from a 90 model 454 SS truck. The shaft measured up 44 inches center to center on the yokes. it has the big u joints in it now im not sure what the exact number was on them. Hope this helps.
