This is what it will look like when you try to put a 750 in the 600 frame, the holes just don't line up and there is no room for any brackets. This has been discussed a million times. There is some cutting/welding required.a friend and i are thinking about swapping a 03 750 motor into a 02 600 frame. is this possible? are the wiring harnesses the same? what do we need to make this work properly?
