Maybe my question should have been when overhauling the front springs, is re-arching necessary? If they look okay, just grind the underside edge of each leaf and the top of each leaf(if the leaf on top dug in and left a ridge), clean up and re-assemble(?). Leaves would get a shot of primer, a brush stroke of Slip-Plate(or like product) and later sprayed with chassis black(or similar product).
If it's not necessary(re-arching), I don't need to reinvent the wheel. Thanks.
