8 3/4 Suregrip Center, and a-body driveshaft

Looking for a suregrip 8 3/4 center pumpkin. Also 8 3/4 shock plates if anyone has a set.

Also looking for a driveshaft for an Early-A body (proper length) since I will be going from a 7 1/4 to 8 3/4, so need a shorter driveshaft I hear. I have a later 904 with the slip yoke btw.

Thanks FABO
