Honestly, I dont know anyone that ever changes their speedo gear when they do gear swaps lol

It's a 9 dollar part and annoying as hell reading the wrong speedo

Without a tire size, that information isn't real accurate.

I'm going through this issue right now, went from auto to t-5 then to tko-500, with 3.73 gear... I e-mailed D&D performance in Mich. but odds are I'll jus wait until I order a new gauge bezzel just so I know everything is meant to work together... besides this sort of work sucks on the floor of your garage.
