[72 Cheyenne K20]

Hi All,

Can anyone please give me gear ration info on my 12 bolt rear end. Have a 1980 Jimmy and the stamped ID from the top of the right tube is:

T A M 058W02

From what I was able to find out: the 058 is February 27th, the W is Warren & the 02 is the Shift. Please correct me if I'm wrong. I just can't seem to find the gear ratio anywhere!


Thanks, Scott
