Ben, part of the problem might be, there are three (3) different iterations of the Mangusta's lower front a-arms! I think Steve ran into this some years ago when he was getting it street ready and found that he had iteration 2 on the left side and iteration 3 on the right. The changes were welding and bracing of the actual ball joint socket in the a-arms, I believe. If my memory is correct, that might be the source of your poor fit. Did you try both sides?
