hello, can someone decipher the numbers I found stamped on my ring gear and tell me the axle ratio? I know I can jack it up and count the turns but where it’s parked right now I can’t or it will roll away. The numbers I found were
97*334 10 41 9-76
The * is a number I can’t make out.
Thanks in advance!

10-41 is 4.10 gears. If you still have the RPO tag, GT5 is the code for 4.10. You can see here on mine is GT4 for 3.73's.

Ok thanks. That’s what I thought but I just want to confirm. No RPO tag on this one, bought it as a frame with axles and added everything else from various parts trucks
