I have a 4:10 Pontiac 31 spline spool that I'm taking the spool out of to put in a '58 29 spline positrac unit. I dont have any carrier bearing races for the 29 spline unit so I tried the ones off of the spool and they appear to be too large. The part number on the carrier bearings are 104949 and the races are 104912. Does anyone know what bearing and race the '58 carriers take?
Contact Fabcraft....you can find them on the internet. Brad knows everything there is to know about the Pont / Olds rear ends and sells parts for them
