Thanks those have good information.
I checked them but they don't relate 80s and up, lugs and floating or not.
Its tough because I have to make sure before I buy a rear end that the brakes tires and wheels will fit. Then i have to find out if the Stainless Steal Brakes I used on the front will work with Stainless Steal Brake upgrade for the rear.
Which they probably will but I donít want to take chances, time is cheap but money is harder to come by.
