Interesting you should ask. I had to get mine done to meet inspection criteria. Dyno tape wasn't going to do it for me, so I looked into obtaining switch bezels like they used to use in 60s Mustangs. But in the end, I machined new bezels large enough for engraving (had to procure specialty taps for the switch threads) only to find all the engravers (including trophy paces) said they couldn't do compound curves. I assume they meant "compound curves that small".

So I went to a sign place and they made up vinyl letters and put them on my bezels. Looks fine, but I worried about longevity. What I was thinking of doing, was to paint the bezels, then peal off the letters, then acid-etch the bezels, then remove the protective paint, then paint just the etched letters.

Another option, is to have some thin flat aluminum photo-etched (laser-etched). Would look like a washer with a tab extending out. The lettering would be on the tab. Install under your existing thin bezels. All you will see is the tab with lettering coming out below or above as required.

But, all in all, I'd check out some of the Mustang sites for the old style bezels, even if you have to buy some switchs that fit.
