Based on that error, the gears currently in your transmission are sized for 3.73 * 60 / 80 = 2.80 rear end gears. Plugging that into the TCI calculator, it indicates that your speedometer drive gear is an 18t. If that is correct, then you'd need a 47t driven gear to go with your existing drive gear. Problem is they don't make that size. You will need to get a 17t drive gear and a 44t driven gear, along with a 40-45 driven gear housing.

It would be good to double-check the number of teeth on your drive gear. What color is it?

17 = red
18 = blue
19 = yellow
20 = brown
