I have a 87 lwb 1/2 ton bagged. the rear will lay the frame on the ground but the front is 4" from touching mainly because the a-arms arm smashed against the bags. thought about control arms, Already have djm 3" spindles. air ride said their controll arms would only drop 2". Is my only option to Z the frame. trying to lay crossmember by may 13th for showfest.
