a 15x8" with 3.5" Backspace will fit inside the front fenders without spacers on either a '52 or '46 that is mounted on an S-10 frame. It depends on the look you want though, a 6" wheel with 3.5" backspace seems tucked in, but then you're talking about using spacers. It might be well advised to wait until your sheetmetal is mounted.
