4 SPEED INTERCHANGE QUESTION

Hi Folks

I have a 3 speed manual transmission with bell housing, clutch, pressure plate and flywheel from a 1971 318 Demon. I also have a 4 speed manual transmission with bell housing, clutch, pressure plate and flywheel from a 1970 340 Swinger.

My question........Will all of these parts play well with each other. That is, can I arbitrarily mix and match the two sets of components I mentioned above?

Thanks FABO
