The Gear Vendors install thread

I reached out to GV yesterday to see if they would provide drawings of the unit with dimensions so I can take some preliminary measurements get an idea of whether or not I would be in for major surgery. I've gotten no response yet but if they deliver I will share in this thread.

My car is a 67 383s 4spd so major hacking of the floor pan would likely be a deal breaker for me.

My question for the FABO Brain Trust is this: I understand that for A-body 4-speed applications a B/E body output shaft is required. Will all the internals of the A-body transmission readily transfer over to the B/E-body output shaft and cross-mojinate happily with the rest of the internals?
