Swapping my clock for a tach… questions??????

[Lonesome7.3]

I have a factory clock installed on the left side of my gauge cluster in my 72 D200. Even though it is in like new condition I doubt I will ever use it. Is there a tach that will match my other gauges and fit in the same location with any mods to the dash or bezel?

What diameter is that cutout? It looks like a 3-3/8" would fit. An Autometer Sport Comp or VDO Cockpit tach would look right at home with those other gauges.

it is about 3 3/5 inches. I will have to see if I can locate a photograph of the tach I mentioned.
