Help Please: 10 bolt center unit on 99 Camaro Can someone tell me what center is in a stock rear end of a 99 camaro Z28. I am gonna upgrade to a EATON Posi and not sure what center I need. Is it a 7.5'' 28 spline?? Thank you in advance.

Stock for 99 is a Zexel Torsen posi 7.5/7.625 28 spline. Your gear set will be a 3 series stock. If you are changing gears at the same time then match the series of the new posi to the series of the new gears. 2 series posi with 2 series gears and so fourth.
