I'm posting a new thread hoping to get some feed back (Thinking about freshening up my suspension). If you have been there done this or know without a doubt the facts, please respond. My ASE mechanic friend and I just spent 6 hours trying to put the rear end/suspension back in to my car, a 1975. I am no further now then I was when I started, just frustrated and pissed. It should not have taken 2 hours tops. Long story, short... I removed the sleeves out of the mustache bar in preperation for my Prothane kit and now realize I should'nt have. I waited 2 weeks for new Oem bushings that are probably on indefinate back order and decided to purchase a used mustache bar instead. Here is the catch, I have a r200 rear differential that requires the r200 mustache bar, but I was told by Z Car Source where I bought it from that the cheaper r180 bar will work fine if you oval out the diff mounting holes and use a lock washer, cool. I am not cheap nor am I trying to cut corners but I knew I could oval out the holes in 5 minutes which I did and be good to go. First of all, the bars look nothing alike. Second, the r200 is much heavier. So, here's the problem.... there is no way that I can find to get the rear control arms to line up with where the bushings fit in. On a 75 the mustache bar mounts backwards from earlier years, I tried both ways. I tried swithing the U shaped bracket around that hangs down behind the diff, I tried it every which way. In the end we feel that we tried every different scenario. Tell me I'm not crazy, has anybody swapped out mustache bars from a r200 to a r180?????
