A big thanks for the tech help ..But.

Mike My cousin had a 66 Barracuda with Slant 6 factory 4 speed In the early 70's. I loved driving that car. Wouldn't it be an easy task to put a 4 speed in your car? I don't know about the early A's but the later the bellhousings are the same. Nothing is as durable as a standard trans for those long drives when your sucking up the A/C. Keep it durable.
