John - I forgot my camera when I went to work on my car today. But I did take a measurement for you. Kingbird has described the differences in the hubs. As far as mounting, the Camaro hub is 3-3/8" from the face of the upper spindle mount, to the outside face of the hub (where the drum would contact). HOpe that helps.
I know that washing and waxing my car with the present condtion of my paint is like polishing a turd.....but it's my turd and I want it polished!
