I just recieved all the parts to finally get this done and I had read on this board about several people having alignment problems because of bent knuckles. How bent would the knuckles have to be in order for an alignment shop to be unable to align the car? I measured the length of each knuckle, and they are within 1/16 of each other, so I don't think they're bent, but how can I be sure before I go to all the trouble to put them on?
