What's up gang? I got a 91 Firebird and the rear end is not as quiet as it should be... recently rebuilt (less than 200 miles)... any shops / people you guys recommend?

I see that Alan Gearworks was once a good place, but it seems Alan has left and now I see a lot of complaints... Only other source I've found is a guy named Richard on craigslist....

Any help would be appreciated... thanks,

Rafael
