Yes, the factory 10.75" rotors clear stock 14" rims. Just be aware that many rims built in the 1960s and early 1970s (both factory and aftermarket) do not clear the disc brakes. As an example, all Olds 14" SSII and SSIII rims will clear, but only the painted SSI rims offered in 1971 will clear. The older chrome SSIs from the late 1960s do not. The profile of the outer rim section of the wheel is different. If you look at the wheel with the tire removed, you'll see a drop-down section between the areas where the tire bead seats. On drum-only wheels this drop-down section is centered between the beads. On disc brake wheels the drop-down section is offset towards the outside to clear the caliper. It's very obvious when you have two wheels side-by-side.
