On my Datsun I have to keep the leaf springs.
Currently my corner weights are
LF 519 RF 450
LR419 RR 416
Obviously I need a way to adjust the corner wieghts. My thought is wider rear shackles so that I can have two rows.of holes enabling 1/4 inch ride height adjustments. Currently the are multiple holes in the shackles but they are about an inch apart.
