I did my disc swap, here are my questions. 1. is the gap between the caliper bolt and disc supposed be this close? 2. Is this a detroit? It has four crossshafts jobbies instead of three like the govloc. and the stock cucv lugnuts are really hard to tighten. I have some 9/16x18 that work great, but the cucv ones suck. Anyone got some insight on this?
