Need Help Urgent Driveline.

[tomsC10R]

I'm installing the 72 BB motor mounts in my truck. They are going to move the motor back between 1" - 1 1/2". I had small block mounts before incase your curious.

Problem: I've only got 1" or just shy of play on the driveshaft yoke coming out of my tranny. Does anyone know if different length tailshafts were made for 700R4's? What about the carrier bearing? Could I make some adjustments there? Maybe move the entire driveline back a little... I've got lots of play play behind the carrier bearing before the rear ujoint. Any ideas?

Thanks in advance.
