Gear Question

I fairly sure the speedo gears for 3.73s are 8642620 and 25513052. Are these the same for 700s and T5s or do the manuals take different gears?

If the WCT5 takes different speedo gears than an auto, does anyone know the correct numbers for 3.73s?

If you are using the 245/50/16 tires, then you need a 7/21 combo.
