HI, I have fitted a 7.5" diff to my chassis
I made the rhs diff plate to the book
the lhs diff plate is different, the bottom mount is to the book but only goes half way up the mount plate .
i made a spacer for the top mount and made a triangular bracket that is welded to the top of the mount plate this is offset.
Im going to try to upload the pics below.

ps i have assumed that the prop flange needs to be on the centreline of the chassis and i havent fitted up the rest of the rear suspension as i havent made it yet lol
