Scott, According to the Chevrolet Truck Data Book I picked up from Chevy Duty, it is 59&9/16, center to center on the front tread.

Remind me to show you the book sometime. I have heard that Novas, Camaros and the smaller Monte Carlos make good donors for rear axles and front frame clips.


Don't lose your head to save a minute,
You need your head, your brains are in it.
