Hey all, I ordered some Astro lower control arms from O'Reilly Auto Parts so that I can install 5/8 balljoints. Ran into a problem during installation. The tabs behind the bushing extend too far. The tab on the rear of the control arm specifically is causing the problem. Because of the extended length of the metal, as compared to the stock control arm, the new control arm will not go back into the pocket in the frame. So, my primary question is, would it be safe to grind the metal on the tabs of the new control arm so that the amount of metal surrounding the bushing is equal to the old control arm? If I grind the tabs down I will be using a 4" grinder with a wheel made for grinding and cutting metal, not a cut-off wheel. I am worried about the heat exposure having a negative effect on the strength of the control arm or bushing. Any input or advice appreciated.
