will a 65 pan motor fit in a 1941-1946 knuckle frame?

Nope. Not unless you alter the frame. You'd have to notch or relief the seat post tube, and also extend it up about 1/2". Pretty well messes up a knucklehead frame to do that.
A knuck goes into a panhead frame okay, with 3/8" spacers under the front motor mounts. But pans don't go into knuck frames without a torch and a big hammer.

The backbone and two places on the seat post need clearanced a little more than a 1/4". The upper motor mount needs to be moved over around 7/32"
