Sorry... only one reference in the search for an engine turned panel. Any product reviews? They seem to have the only 5" gauges on the market. Need a set to fit standard openings in a '38 Ford pick up dash.
Haneline has the big giant 5-in-one and I beleive that the 5" gauges are 4 3/8 in mounting hole. They are imported, but at least they merged with Nordskog, an American company Mark
