I was not planning on mating to any mopar transmission. ..

Sorry for my confusing sentence. I meant that you can't connect a Dodge Magnum V-8 to a 1965 transmission without several mod's. One is a spacer ring so the torque converter snout fits tight in the crankshaft hole. Another is to mount a crank pickup in the transmission bell-housing (cut slots). All Magnum swaps I've seen use the later OD transmission, which loses the 1965 shift linkage.

Shortening a driveshaft is fairly easy and there are conversion U-joints to mate some driveshafts to other-sized differential yokes. A six-speed Tremec would allow the shifter to just stick up thru the tunnel and I recall there are aftermarket handles to optimally position the handle. Might have to fab a clutch pedal. Tremec might have a hydraulic clutch or perhaps retrofitted with one, so no fussing with linkages. Others have swapped an LS into an old Mopar so google.
