    Anyone know where to find the rear axle gear ratio on the option code label? I have a 2wd 1986 Chevy S10 w/ 2.8L & 5 spd OD tranny. Rear axle tag says 4.10 ratio but speedo is way off. I think someone swapped rear axles at one point and I want to put in the correct ratio again that came stock for better gas mileage (this truck will be my commuter).

    3.73 is very common with 2.8L/5-spd combo.
