Yeee doggy

An 8.8 Ford rear end is exactly that, an 8 3/4 Mopar rear end is exactly that, and there is a definite visual difference. The 8 3/4 never had a 5 x 4 1/2" bolt circle unless it has been re-drilled, or has aftermarket axles. Most of the later model 8.8 rear ends had disc brakes, whereas the 8 3/4 rear only had OEM drum brakes.
