I've got a '64 Barracuda that's getting a 5.2 and an A500. Motor and trans are in, but the project stalled out a couple years ago. PO had chopped out the torsion bar crossmember and the hump to install a 727 (still don't understand that), so the "no turning back" line was already crossed. I made my own tunnel, but I've no idea how much of the original could have been saved since it was pretty much gone. Orignal bucket seats should fit fine, however.
