I just installed some new Mevotech upper control arms. I have 2 issues that I need some advice on. First the bump stops will not stay in the slots when I let the jack down. Second I messed up and let the shims fall out before marking them. Is there some way to get it shimmed close enough to take to alignment shop. Also what are you guys doing with the abs sensor on the Blazer setup? Any help will be greatly appreciated.
