If anyone knows how to look up part numbers I would really appreciate it. It's a 3.73 Richmond gear part #:80-0452-1. I have a 1999 Chevy V6 Camaro 5-Spd. The stock gear is a 3.23. I just need to know if this is the series gear that will fit my car....I am really in the dark on this.

Go to a junkyard and get a 3.73/posi out of a Blazer. Its cheaper that buying a new gear/posi.

 

Well I wish all websites were as easy to navigate through as Richmond's was. I figured out what series rear end I had, and if the gear would work in my car. Happily it will fit, and I am going to get it installed immediately.


Regarding the condition of the gear.....It has been sitting in my garage for about a year now. Is there anything that I should do to the gear to clean it up, as it is kind of dusty and grimey. (prior to installation)

 

id say just spray it down with brake cleaner and make sure everything looks good
