The Magnet Clamp Screw access hole is pictured below at the tip of the screwdriver. If it's not there, the answer to your original question is no.

Jack, my case could have been as you described and I should have changed them all. Frank didn't say.

There are very specific metal requirements laid out on the Ford drawing below. I have no idea if the "brass" is "correct" in what is available from the vendors today. We may all be flirting with disaster with the "new" brass screws.

However, I am suspect of suppliers furnishing 1/4"-24 brass screws for #14-24 which was the case in the past. I know a "/" is not a big deal, but if they can't get the size correct, what's your guess on the metal which should be the real question on this part!

No telling how many 1/4"-24's were forced into #14-24 flywheel and starter gear threads. I just looked at some #14-24's I was sold years ago and they DO NOT match the drawing.
