Hello all,
I will be doing a rear diff housing swap on my 82 Z28 soon. A friend of mine is giving me his freshly rebuilt 2002 Z28 rear housing as he is swapping up to 3.73s. However, I don't want to spend much money on the car right now, so I want to reuse my current backing plates and brakes.

Does anyone know about the backing plate bolt pattern difference between early 3rd gen and late 4th gen?

Also, has anyone done this or a similar swap? Anything I should watch out for?
Thanks in advance.

 

The main difference will be the fact the 4th Gen rear is 3" wider than the 3rd Gen rear. You will need wheels with an offset in the range of 50mm.
