Re: GMC rear end wider than chevy's?
I don't believe that's true in any year. Gotta wonder why they ever would.

71 and up rearends were 1 and 3/4 inches wider because of disc brakes on front

5-lug? 6-lug? Measure between the backing plates. It will be either 55.5" or 57" There was an early rearend (55.5") and a late (57") rearend.

Re: GMC rear end wider than chevy's?
I think its 57" if I measured correctly.
Its 57" when I measure from point number 1. its that the right place to measure from?  If it is 57" and I want to convert it to disc brakes will it get 1.5" wider? |
