need help with axle ratio
i have a 1972 gmc c20 292i6 4 spd manual reg cab lwd i need help trying to figure out what my gear ratio is, i am told that it was a 4.56 by original owner i found these numbers and letters, here they are sorry some pics are upside down.
c34950 2 60-3b it has ten bolts im pretty sure its a dana 60 hence the the 60 num
i used a formula to figure out my ratio using my rpms and mph and i came up with 5.3? i thought maybe 5.13? but didnt see it as option for dana 60
