Hi All,
Where can I find a pictorial location guide to axle and differential codes? I have a (what I think is a 1974 rear end) with the following codes on the center housing: E318, GM24 and 1254338.
The code on the axle tube is: 2 PT G81531.
Are there any other codes I should be able to find. If I knew the locations it sure would help. There are ton's of help for the 1967-1969 camaros but I have been having a lot of trouble finding the 2nd gen info.
Your help will be greatly appreciated,
Ken

You can find information on deciphering what you have by the casting number Here

or Here

1967 Chevelle Rear Axle Codes

According to my Chevrolet by the Numbers 1965-69 and my 1970-'75 edition it decodes as:
PT ====> 1975 Camaro 2.56
PT ====>1967 Camaro 3.73 with metalic brakes
G =====> Detriot Gear & Axle
Both left the factory as an open rear end.
