i have a 1991 camaro rs , built 350 .040 over .it has 4.10 richmond gears with a eaton posi cage. 28 spline axiles. it has classic platers so i drive it mostly to car shows. its used mostly on the highways ,so the gears are to low for my liking. question; i do all my own work but never messed with a rear end. can i just change out the ring and pinion, with some3.73-3.23 gears and keep the posi cage i have now. i do believe i can. and does it take any spiecial tools or parts to do so. i have read that you may have to shim the ring gear. how hard is it to do. Thank you for your responses.
