7 1/4" to 8 3/4" rear end swap advice
I just did this a couple weeks ago. Used a floor jack.
You will need different shock plates, the 7-1/4 plates are different than the 8-3/4
My rear came with parking brake cables and hose. So I have no idea of differences there.
I just had a new drive shaft made and it was for a Barracuda with a 727 so the length will not be the same.
