Well i tried my hand at refurb on my tach came out pretty good least ways it works. I'm looking for the glass for the gauge. I'm going to try that hot rod John that Steve turned us on to. He has glass for 2 5/8 gauges. I think that is what the tach is. My first gauge had the glass the second one I'm doing the glass was broken.

I think I'll try the instrument panel next. se how that comes out. I'll try making decals and see how that goes.

PS Autocar did you ever get your tach to work right? . I'll bet it's just dry. there is a piece in side with a plug and a wick. You may just need lube.
