T5 with 373 gears which speedo gear?

[MyBlackBeast]

I searched but i got alot of mixed answers. Some people say 23T white gear some people say 21T red gear. I just rebuilt my T5 i know it has a yellow gear on the mainshaft.

I have the same set up, get the red 21 tooth gear part # C40Z-17271-A.

red.

white is for 4.10's, although it still is the incorrect gear to use with them with a yellow drive gear.
