I appreciate the reply. I was referring to the GM oem wheel. Fitting around the drum in the rear can be very flexible, but in the front the tie rod ends and calipers are probably going to dictate the maximum distance in order to clear. The GM axles are wider by about 2 inches and I'm trying to determine whether there is enough wiggle room to make that up with additional backspacing on the rims. Doesn't look like it, so the wheels will be just a little proud of the fenders. Oh well, at least I can find parts.
By the way, to maybe save the next guy time on research. The backing plate/dust shield for the 3/4 ton GM disc brake setup is not available in the aftermarket. All the rest of the pieces are, but not that. Mine from the junk yard were bent, but a little heat and hammering and they are good as new - almost.
