I have just aquired a 97 cobra that has had a few mods done to it and still not sure if i made a mistake or not. my thing though is im worried about the rear end right now. the cobra i have has had a tranny swap it now has a 6speed demon tranny in it and has had a performance suspision put on it. My question for now is are the rear upper control arms a must have on the car or is there something that can replace them? Im asking cause my car doesnt have any upper control arms on it. please any help or advice is much app. thanks
