Car all rebuilt with nice new arms and hinge pins.
Although I'm going to stop putting bushings in on the arms. They are stupid expensive and break too easily..even before the hinge pin bends.
Yeah good shout on the length.I'm not sure why you're having the the bushings break on you. I've personally yet to break one but have definitely bent pins, bent hinge pin blocks, and broken an arm or two. I have seen them break, but it's far from a common thing.
With regards to running without them - the hole in the arm is much larger than the actual hinge pin and running without the bushings is not a good idea. The arms will have a significant amount of play in them causing inconsistent handling. It will also cause the arm to wear out faster and be more likely to break. Also, since they bushings rest on the outside of the arm and the flange is 1mm thick, your arm would be 2mm shorter (front to back).
