You need just one copy of the file in MODS folder. It doesnt matter how you acomplish that... either create a separate mod for it or include the modified file in one of the standard mods.

I have it separated and I have a speedbar smaller increments mod also... I don't have one that transforms Km/h in Mph though.

If you want I upload a copy of my 2 mods... for exemplification.
