65 4 speed in 71 Duster?

Its been done before. One of my instrument panel customers bought a Demon and discovered it had a early 4 speed trans. Custom made mount, drive shaft, shifter linkage, were required. Probably clutch linkage too. Only thing that hadn't been conquered by the previous owner was the speedometer cable. That piece had to be custom made also.
Most of that would apply to the A-body 4 speed too.
