Factory Tach Question

[48richard]

I am putting together a tach (and clock) dash using a Camaro tach. The Camaro tach has white numbers on the face. My question is - does a factory tach have any numbering painted on the face, or is it all on the lens? My thinking is if the factory numbering is all on the lens, and if the sweep of the tach is the same, which I believe it is, I could paint over the white numbers on my Camaro tach face, use a factory tach lens, and end up with the correct green numbering.

Thanks.
