Clutch Fork ?
 

Can anyone tell me what clutch fork to use with a GM bellhousing #3925505.
I tried one from AutoZone,their #cf-100, but it wasn't long enough. The throw out bearing was about an inch from being on-center with the clutch disc. Thank you for your help, again.

That part # bell housing comes up as a cast iron unit used in 68'-72' truck applications. Try a fork for a truck from that year with a V8.
