68 Barracuda Slant Six Automatic Transmission

Do an A833 4 speed O/D out of a Volare/Aspen with slant 6. Then you can use an A body slant 6 zee bar, 67-72 A body clutch pedals, down rod, and 67-74 A body floor shift plate. Stock A /F body shifter should clear a bench seat.

This way you can use this transmission for a V8 later on if you swap one in. All you need is a V8 bell housing, flywheel, etc. Then you will have a bonafide V8 4 speed swap.
