Depends on what style you are going for.
Billet isn't going to work for a 60s vibe.
Chrome fits better with that era.
If you are going with a smooth look, bright color (Viper Green is up there ) and a low stance, that's more 90s style. Go with a more modern and monochromatic look.
A stock panel with 2 new race gauges will not work for an early look, that also leads toward a more current look.
Here's a stock plate. I think with some effort, you could make a nicer one.
