Has anyone done the Classic Performance Products disc brake conversion? Mine is a 1952 GMC 1/2 ton. I started on the passenger side and was ready for assembly as per the mickey mouse sheet they gave me. ANYHOW, I used my old bearings cause they looked good,and I am basically cheap. I put the big nothched washer on and started to tighten the main nut. I have about 3/4" thread sticking out so far and the assembly is still wobbly. Seems like I'm missing something but I haven't a clue what...Tech line is useless. Any help?
