Those are 2-1/16" gauges. For the panel, I built up a wooden panel that fits exactly into the radio mounting holes. It doesn't look quite so good from close up actually, as I didn't get the surface perfectly smooth, nor does the paint exactly match. But I figured, not bad for the first try. If I built another one (as I mostly likely will because I'm REALLY tempted to put another gauge in there) I'd fasten the mounting brackets into place first, THEN glue the panel on, instead of taking measurements off the radio and building the whole thing first, and making it fit later. I think I have a pic, lemme see . . .



yeah here's a fuzzy pic of the back of the panel . . .

 

cool. looks good. thanks.

i order a nice aluminum piece made to fit 3 of those gauges that would also accomodate a radio on top...im guessing it would have looked nice.
