Period correct dash clock?

[Praxiss454]

Hi all,
Been thinking it'd be nice to have a clock in my instrument cluster. Someone already put in an aftermarket tach on the left large circle, and I've been thinking of using the right large circle for a clock. Can't seem to find an original one anywhere (OEM Part Number 2233890), so I was thinking of trying to find something that'd look good enough for my old clunker.

Wondering what you all have done for your dashes?

The factory clock was made by Borg instruments and there are other clocks made in the 60's that are basically the same clock and dimensions just the faces are different. I'm including a pic of a Studebaker clock that is very close but with smaller numerals sitting next to the GMC clock.

Thanks, do you happen to know the dimensions I should search for?

Here is a shot of my dash layout with an GMC OEM clock and Tach.

It should be 3 3/8.

Well, not seeing much on eBay that looks like the correct diameter, but I guess this is the kind of thing you gotta be patient for. I don't *really* need a dash clock, just thought it'd be a cool thing.

Off topic, but the original water temp gauge in my dash is not working. When I turn the ignition on, the needle moves, but at some point someone hooked up a different temp gauge and must have unhooked the original one. Wonder why...
