Those are pretty sweet. I think they'd look better without the blue band on 'em. IMO, blue's being over-used these days on the dash lights. Ultimately, I like 'em because they're different than what's currently available. I like the font you used.
What I think would REALLY look cool would be some '70's style numbering, like the Mach 1 'stang, also like the retro gagues in the new Mustang.
There's just something about the old classics that always looks good.
