I have an Eaton Posi---# EAT19556 for 3.73 & up. From Randy's Ring and Pinion. Paid $330 in 2001. The truck unit is different I think. --Jeff

Re: need info on what posi carrier i need for my 65 shorty

You just need a 'posi' unit for a truck 12 bolt. They were built from 1963 thru 1982. Which series depends on what gears you want to run. The 4 series carrier is for 3.73 and higher numerically, and the 3 series is for 3.42 and lower numerically. There are several different posi's, lockers or whatever you want to call them. Here are a couple of websites to look around on....
