Help with a RPO number
I am looking at the service parts identification sticker found on the left inner fender on my 73 GMC.
It has a code 1ZN8 for an optional axle ratio. I can't find that code any place and I have searched the net up and down. Can anyone help me with this code? Thanks all.

It will end up with a nice strong 454 in the end. It has not been run for 20+ years Frame up restoration started2/15/2010 |
