I figured I would come here to ask since there is a discrepancy amongst the speedo gear calculators I have found. I was told my '91 Mustang was switched to 2.73 in the rear when I purchased it. Speedo is not working right at all and I know I need to change the speedo gear because I passed one of our roadside police speed displays and I am off by more than 10 mph by what was showing on there. Someone told me I should get the yellow 18 tooth gear because that came stock with 2.73 Mustangs. Others have said I need the white 17 tooth gear. I have not pulled the current gear out to see what is in there. Just wondering if anybody else has had experience with this.
My car has:
2.73
215/60/16 tires
8 tooth drive gear (90-95 aod and aode)
