Which trans do you want?? Mummert does a C4 bell for C4 and conversion for T5 using stock bell. Quicktime does a bell conversion for T5. Bendistien does and adaptor plate targeted at Ford AOD but with flywheel or flexplate changes you could adapt any Windsor or Cleveland trans. Some toploader 4 speeds are a bolt on with just a clutch plate and crossmember change.

What's it going in there is a difference between car truck and bird?

cheers
