Hey..If you're talkin' bout the CENTER of the gauges and the outer BEZELS...that light brownish color...(my 52) I found a spray paint so close it suprised me...It's "AMRICAN ACCENTS" by Rustoleum,the color is #7948 'London Gray'.It aint gray...it worked very well for mine. (along with a decal kit). Oh yea,the paint is a 'satin' wich matched very well.
This post isn't intended to curl anyone's nose with the nice paint guns and bucks-up paint...spray paint works pretty good sometimes!
