I have in my notes ~0.625" front, ~0.75" rear. It's also what I indicated on my last wheel order form, so I must've measured it at some point.

I don't have a direct answer, but will offer some input anyway. I am running Weld Draglite wheels on my 80. The Welds mounting surface is almost flat to the wheels center. This is a problem for us Vette guys because the brake caliper over hangs the hub on the car by a little over 1/2 inch. I say that because to mount my wheels, I needed to install 1/2 inch thick spacers, use longer studs, and the wheel would then fit the car. This is why you can not just go by wheel back space. The wheel backspace is measured from the wheel mount, to the wheel rear rim edge, and does not take into consideration the brake caliper. It also explains why so many Vettes run American Racing TTII wheels....They fit without mods.
