Simplest trans removal and install

I put a 3spd in my 65 valiant. It was a chore knocked off upper ball joints lowered k member. Now I picked up an od 833 out of a van I grabbed everything from slip yolk to flywheel . I have two questions 1st do you guys know of an easier way to install the 4spd without tearing it apart again, or should I just pull out the engine.2nd can I use the hurst shifter that was on the van with the linkage for my car.
