GMC Rear End Codes?
Does anyone know the rear end codes for GMCs?
I found all of mine. Option Code is: 4G80AC Rear PosiTraction A Pass. side rear: 67890 and 126 4 5 on top, stamped is TPP0213 W an E slanted above the "3" area front side is NF 3896839 on Driver side is: A 29 0 I assume means Jan 29 1970 and GM 51 I have searched every where I can think of and can't find anything else on it. The Diff cover has 12 bolts if that matters. I have been able to decode everything so far as best I can except the rear end. Thanks for any info/help. ![]() ![]()
