I figured you just didn't want the camber.You can lay without them on 18's.I ran into fender clearance and lift issues when I had them on my 92.My old B2200 lays flat on 18s with stock spindles and flipped lower ball joints.
This is my old 92 stockfloored that I had spindles on.This pic was taken at full lift 145psi and it barely clears the 16s.Just trying to save you from a headache later.
