does anyone know why front lower control arm part numbers are different before 82? I know that is when the metric change over happened but if you look up the bushings and the ball joints separately they are the same in all years. The reason I need to know this is because I am restoring a 79 malibu and I need to get new control arms, but they are only available from 82 and up. The upper control arms are the same way. If know one answers the topic I guess I will just order one in and compare measurements. I have to thing it has something to do with the metric change over but I can't think of anything else besides the bushings and ball joints. weird.
