It's not the backspacing of the rim you are talking about it is the hub thickness of the rim. Backspacing is the distance from the mounting surface to the back edge of the rim.

You can knock the wheel studs out of the axle and replace them with longer ones. There were several different knurl diameters so you will have to knock one of yours out and measure it to order the right ones.

The C-10 should use 7/16" threads so look up a 75 Corvette in the parts store to get one of their wheel studs. Theirs are about 2" long due to the design of their brakes so they should be longer than yours and may be the same knurl diameter.
