Since the HAMB was down all day I went on a parts trip and picked up a nine inch rear end. I've not measured it yet but the guy I got it from though it was 58". Have to put a tape to it tommorow. He was not sure what it was out of but thought it was mid sixties. I'm happy I found one and it is the width I was looking for....but its an off-set center section. It will work...but I hope it looks okay when finished. Time to order some parts from Speedway!!!
