318 three speed help!

...............the pilot hole for the input shaft will likely be too short for the trans input shaft, which u can shorten a bit and also the pilot hole will be too small in diameter, so u will need to get a bearing that fits in the crank register from ma mopar, mancini or other parts places.........kim........good luck with ur swap...........have u given thought as to what motor mounts u will need......Schumacher Creative Industries makes adaptor mounts for ur swap
