New (to me) C10 that has been touched more than a few times so I'm trying to figure out just what it has in it since the PO had now idea.

Re: De-code my axle please.
If you have a GM truck parts book, vintage '78 print date, starting on page 61and continuing to page 68, it has a complete rear axle id chart with ratios per the code. VA72C10 pm me your axle codes and I'll look'em up.

Re: De-code my axle please.
There used to be a website I used, but it is no longer functioning.. It just happened to be I had copied a few down when I was looking for a few of my codes..
If you can find a Hollander interchange manual that covers our years, It also has the infomation Here are the few I have RHA= 1972 3:07.1 RHC= 1971 3:73.1 THC = 1971 3:73.1 You can also go to GMC pauls website for 67/68 codes |
