12 Bolt Differential ID Identification Help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ADimas · 08-21-2018, 03:59 PM

I am trying to figure out where the differential on my 1969 C10 Step Side has. I have gone through the search on the board and the other postings I found do not match anything on my differential.

That being said here is what I have stamped on it.

Passenger Side
THC W138 2
NF3896838

Driver Side
GM 61
CN3

I tried attaching the pictures but for some reason it says missing token.
Here is a link with the pictures any help is appreciated.
