Quick rear end help...

And I probably will, was just curious as it's a 3 hour drive one way. The 52" had me thinking he was just rounding off as the only axle in that range is an a body
Ask him if it was cut for a custom setup...A body is the narrowest at 52.625". If it has a center in it, he needs to use a straight edge on the flanges to get accurate measure.
