A few years ago I did a 73-76 disc brake conversion on my 66 barracuda. When I got the set up it didn't have the upper control arms, so I purchased a set of new aftermarket stock replacement arms. Due to other things going on I had to put the car away for few years. It was assembled, but not aligned. I'm finally getting to the alignment of the front end and find the ball joints are toast. The bushings didn't look all that great either. The car has only driven out of garage to the street to be put on a trailer, so no actual mileage. I was disappointed to have to tear into it again, but needs to be done. So I figured I would start over by replacing with Moog ball joints and installing offset bushings. Problem #1 my ball joint socket didn't fit. The ball joint is too big for my socket to fit on. I know my socket is correct, since I've used it on other ball joints. Problem #2 the holes in the arms for the bushings are .030 smaller than the new bushing shells. There is no way in hell the bushings are ever going to fit. I haven't received my ball joints yet, but suspect they are not going to fit either. How f***ing hard is to duplicate a part with known specs? I can't remember what brand they were or where I got them from, so I can help others avoid them. Time to post a want ad for oem arms.
