12 BOLT AXLE CODES

[Tom Hartman]

I am trying to figure out what gear ratio came original in my 1969 Camaro 12 bolt. code is as follows
PF 1101G
E
All I have come up with is the gear set is from the Chevrolet Gear and Axle plant and the "E" is for an Eaton psoi trac unit. Any help would be appreciated.

Thanks for the reply, is there a list of the axle codes somewhere?

Thanks, I would say by the looks of the list I better check my date code, it is probably a '67 12 bolt in my '69 car. I know it is not original, but didn't think about it being a different year.

Yup, it a 67 if it's a 12 bolt.
A 69 PF was a 10 bolt.

I will crawl under that rascal tonight and check the date code.
