B/C Body 4 speed into an A-body.

I have a one of those adapters for a B/E transmission already fabbed up. Using the B mount is not a great idea because the upper mounting bosses interfere with the torsion bar crossmember. Find someone that would be interested in swapping the B only tailshaft for a B/E tailshaft and you are good to go with an adapter plate. They work very well.
