'69 Barracuda T56 swap, floor, cross member
I copied 72bluNblu and pirated his idea to add 3" holes above tranny to access top bellhousing bolts. I plug the hole with a body plug. It sure makes it alot easier to drop the tranny when needed.
2 things I found were the automatic carpet was looser than I had hoped, but it will do the trick.
The shifter seems very close to the bucket seat in 2nd gear, but I could find an offset shifter or just carry on.
I also put the American powertrain reverse lockout control under the driver seat. Later I found Bowler transmission makes one that is smaller and mounts on side of tranny.
