Couldn't stand it so I pulled the cover off of my final drive and it is clearly marked 1373166-14-45-GM
I counted ring gear teeth and there are 45. So I'm guessing I've got something strange or a little better than stock or both. Something else, the gasket I got from Nick at Applied didn't fit the cover so it went on with RTV. Also does anyone know where the SN is on the tranny? Any input on either subject would be welcome.
