Rear end change
Rear end change
I have a 91 z28 with a 305 motor and auto tranny. The original rear end had 2.73 gears. I have a 89 iroc rear end with posi and 2.77 gears in it now. It whines a little, but the speedo is off. I know I need to change the gear in the transmission. But any ideas how to find out what gear I need. Thanks for the help.
