Here's some that I have.
The black one has been powder coated. I have 3 of these.
The others are Eelco. Look up Eelco gauge on eBay and you will see quite a few.
One of mine has the holes opened up to fit 2 5/8 gauges. The holes still need to be opened a little more to fit 4 Sun gauges nicely.
I set 4 gauges in to show how it can look.
I don't like that some have little holes for lights of your choosing.
Back in the day, some were used to illuminate the gauges that did not have lighting in the gauge. You'll see that on eBay.
It will take some work and careful measuring to open up the others to fit 2 5/8" gauges !!!

I may have an extra NOS 2-5/8" SW 3 gauge panel....I'll check tonight.

I thought "Most" Yenko-installed gauges in 69 were 2-5/8" Greenlines with some 2-5/8" black face, and a few 2-1/16". Not sure how I developed that opinion, but I'd love to hear other's observations.
