If that involves a piece of seat post tube shoved down to the mount point so be it.
Just make sure the back motor mount is one with frame and go from there.
Front mount being correct is important, but the rear mount being "one with the seat post" is very critical and will be the straw that broke the camels back if not done right without rubber or things similar between engine and frame.
