I think you may have a problem with the length of the trans. The a body trans is much shorter than a B, E, and probably Truck transmission. Before buying anything more - verify what you have - this will get very expensive if you choose to change the trans over to the shorter A body style. You will need a new or good used main shaft and a short tailshaft extension housing. You can not install a B, or E body trans in an A body they interfere with the torsion bar crossmember. I found this out the hard way 25 years ago.
