I don’t. It was easy finding the right tap by running the ball stud into a die. I tried a couple different drill bits on scrap metal before I was satisfied with the fit. I’m almost certain it’s a 1.25 thread and probably a 8mm.
For anyone who stumbles across this now, since posting the thread I updated it with McMaster part numbers that are still current. It's what I use now and they work very well, now without contacting the wiper arms.
I just did the Arana struts from Amazon, worked perfectly.

The lower ball screws in to the top rear hood spring bracket on the fender, and I drilled a 1/4" hole using the factory pinch weld dimple just above the existing hole in the hood. Tapped with an M8x1.25 thread, and the upper ball screws right in.
