carrier and the rear axle bearings. Thanks

What are "fender carriers", do you want the outer axle bearing part numbers? | | | | | Joined: Apr 2020 Posts: 13 'Bolter | | 'Bolter Joined: Apr 2020 Posts: 13 | Sorry, voice to text got me again.
I am looking for all differential bearings. Center carrier, axle bearings outside by the backing plate and there are 2 on the pinion in the torque tube.
6 bearings with 4 different bearing numbers
It's for a 1941 GMC CC101. Chevy 1/2 ton is the same differential.
Thanks.

I’ll try to look again tomorrow
-s | | | | | Joined: Aug 2018 Posts: 1,003 'Bolter | | 'Bolter Joined: Aug 2018 Posts: 1,003 | assuming "COMM" means it's the 1/2 ton truck, then all the numbers are still the same as the earlier post, often there is no "1/2 ton" listed for 1941 year specifically
someone with more knowledge of the parts books abbreviations should comment
