ok i want to go from 273 factory gear to a 373 gear, dose any one know what other ring and pinion gears will work besides 3rd gens or dose any one have one for sale

 

First you have a 2-SERIES Carrier. Unless the 3:73 gear set is made for 2-seres (thicker gear) it will not work. You will have to seach for the thicker gear sets or change to a 3-Series carrier.

 

most s-10 blazers have 3:73 gears and a gov-lok limited slip. you can purchase a junkyard rear for about $150, then have a professional swap the carrier and gears into your car. that is year dependant on your car, i dont remember what year camaro went from 26 spline axles to 28 spline. you could also try to find an f-body rear with those gears already installed
