Y50 rear bumper Question

Hey guys I recently had a small accident on my y50 and my rear bumper is gonna need to be replaced. Its a 07 and I was thinking about replacing it with a 08+ m35s rear bumper does anyone know the interchangeability I know there was some small changes on the taillights but everything else looks pretty close I've tried searching with no exact answers. Can someone help me with this?
heres my current bumper
