First time on here guys, Need a Posi rear end for my 91' Formula restoration project. Will a 93 and up rear end work on my car or would that be too wide? (dont want the tires sticking out of the quarters like some hillbilly's have them)

 

Welcome to TGO. Questions about width, combination valve, parking brake cables, speedo gears and so on can be found in the following link:

BTW, since there isn't much on TGO that hasn't been asked and answered, a search is generally a good idea.

Best of luck with your project.
