What is a good differential??

Well I just found out that the differential in my 89 Iroc is a negative one. And I know that a positive one is better, but I don't know which positive one or where to get one I want to get one in these few next weeks, soplease advice me on the subject. Aslo you may have noticed that I don't know alot about the subject so if u could also fill me in on the subject I would appreciate it. thankyou

A negative one...huh? Do you mean that it's an open differential and you want to get a rear end with a posi differential?
