I have to ask. I've never seen one in a car, and I've never seen one for sale.
I don't see them in the parts catalogs repopped.
This is the big pod clock, (for lack of a better term). The console was made for this option because it has a special little dimple the base sits in.
I've had this one for years. It's factory.

I have one of the clocks and the part of the console it was attached to.When I purchased my vert back in 82 it had been converted to a factory guage console and the guy gave me the clock and piece he cut out of console.The clock didnt work so he saw no problem with it.Beside back then 100% original was not a big deal!

Steve i sold one back in feb. at the swap meet for 100bucks,,just the clock and mount not with a console, not really sure what one is worth, i let the buyer price it, Frank

Frank, $100 is not bad for just the clock. I say it was a deal for the buyer.
I paid $50 for the console & clock 17 years ago. I know something is only worth what somone is willing to pay for it. But it seems to me there aren't alot of these floating around now.
I wanted to remove the clock & mount my 5" tach there, but I'm not sure now that I'm going to molest it even with screw holes.
I think I'll have the clock redone with a quartz unit.
