The 12-24 thread size is not common in hardware stores. Not to give a sales pitch but we sell them...

That's exceptional! As I commented, it's just the one that 'refuses to cooperate'.
A member suggestion, dremal the head off.
But that still does not result in enough screw grab-surface; although then the dash could be removed for woodgraining.
When I posted this post(s) about the windshield removal to replace the cracked plate-glass, and that now would be the time to remove the dash for woodgraining, I did not realize the cost of woodgrain'g a dash and the three window mouldings.
I just now received a quote from a most professional woodgrainer whom I contacted for a price and photo. It's outta the ballpark for me. I'm stunned. My wife has been 'forgiving' on $ spent so far, but this woodgraining price will be the 'last straw', so I had better do the hydraulic brake system as well as the presently all-over-the-road steering 'problem (steering prob which = the drag link-pitman arm).
The graining example photo is excellent-excellent, 1933 burled walnut, perfect perfect. thousands thousands!
and so not now.
So, I will continue to delve into this stubborn-screw, as long as I am 'into it'. I do not want to leave the 'task' half done, and 'close it up' because it is a nightmare; not exciting to come back to. AND, it's anybody's guess if in fact I can actually get it out.
Despite, I will purchase your (6) screws just to have them on hand for the one I will need.(thinking positively) What is your payment suggestion. (Personal check to be 'cashed' by you prior to sending the six screws?)
Thank you,
