Hello. Just thought I would join this forum and see if you guys can help me out.

I have a few rear ends, and not sure what they are.

First
1996? Chevy 14bolt Disc Brake Rear End AAM 40006189G 3276 8 Lugs

Second
1984 Chevy 8 lug drum brakes 14 bolt 26004797

Third
1987? Motorhome 70HD c37453

Fourth
1996? box van 10 bolt 8 lug c37453 ohol

Any ideas? I cannot find information on these. Pics will come soon if needed.

Thanks and glad I found this site!

 

Try drivetrain.com that is where I found my numbers. Good luck in your search.

 

You have already identified what they are, are you asking what gears they would have in them?

 

I want to know if they are dana 60 70 80 etc and what the codes mean. I would love to know the gearing too but I think that is on a little metal tag that I cant find

 

This chart may help you. http://www.4wheelnoffroad.com/axle.html

 

Hey rob17san,

Welcome to the Chevy Forums.

The RPO codes in your glovebox should give you some information. There's a Glossary of ROP codes in the Tech Section of Chevy forums.
