65 Barracuda k-member swap? & rearend

If you're doing a /6 to small block changeover you'll also need: Accelerator pedal assy, and cable; all the correct mounts and brackets for a '64-6 A-body engine; Correct kickdown linkage for same (2bbl or 4bbl, as they are different); V8 radiator, exhaust system; and other recommended upgrades such as disc brakes; bigger torsion bars; and 6 leaf springs. If you get the 8 3/4 out of a car, grab the 6 leaf springs and the u-bolts and shock plates too. That donor car might also have the bigger torsion bars.
