I have 9 bolt 2.77 posi in my 88' ROC, I'm kinda new to the modding stuff but I read somewhere that 3.45 or 3.73 won't even fit if I have 2.77, so I'm probably going to get a whole new 9 or 10 bolt rear end with 3.45 or 3.73, looking for something that isn't too expensive and gonna cost me alot of money I'm a full time college student so I don't have much I still owe my parents back for the car, heh. Anyone have anything good that will fit? Ebay doesn't have crap.
