That sounds about right Joe. I measured the same when I was hunting down a
rear for my 53 1/2 ton.
I also checked the width of my 72 Chevelle rear and it was pretty close to the
same width as the AD
rear. Unfortunately, I wasn't about to strip my Chevelle for the parts! I
ended up with a 10 bolt
posi from an '85 Camaro Berlinetta that was also a similar width. All it took
was grinding off the
old coil spring perches and other flotsam, and welding on the perches from the
truck springs. I
went with an aftermarket spring replacement from Chassis Engineering. I have
not had a chance to
drive this rear end, but I rebuilt it with a new Richmond gear set, 3.23:1
ratio. I don't plan on
many tire-shredding burnouts, so the 10-bolt should suffice.
