Question for anyone that has done a cucv front axle swap into our trucks. I made new spring hangers so as to line up with the factory gm perches. I know our springs are narrower than theirs but has anybody welded in a shim to the side of the diff. housingso that the leaf spring is up against something solid. I don't know if it needs it but it does leave about a 1/4" of room between the inside of the spring and the diff.
