I'm not sure about the backing plate, as the axle mounting bolt pattern may be different, and possibly a different offset. You already have the correct brakes, and it looks like the A- or G-body (and Camaro) 9.5" drums are the correct depth, compared to the Monza, according to the prints. The worst I've heard is that you may have to grind a little off the outer ring to clear the groove in the backing plate.
