Help with 360 swap?

This motor mounts are hard to come by I’ve got my feelers out there. Was planning on a new full dual exhaust and a new radiator the one in there now is tiny and seen better days. So the trans pan that’s no there now being out of a motor home you think will fit
Didn't get your last statement. Pictures show it to be a normal tailshaft. Then you'll need a shorter drive shaft because 727's are longer than 904's
