attachment hardware on 3-bolt to 2-bolt adaptor distributor plate (solved)

i'm in the process of removing a recently installed 3-bolt to 2-bolt distributor adaptor plate on my '41 ford super deluxe.

as of now, i've removed two flat slot-headed screws that are countersunk into the adaptor plate. the plate is loose but still attached by a third screw of some sort.

the third attachment piece of hardware is different. the hole is only about 3/16" wide (i can't see into it) and i suspect there is a grub screw in there with an allen head. can anyone confirm if that's how they were made and that's what i'm dealing with?

the adaptor plate's aluminum, i think, and the two-bolt distributor attaches directly to it without issue. problem is, i want it off, and returned to the original three bolt attachment arrangement.

and i'm assuming all three of the original holes in the block or timing cover have some sort of insert in them, especially the one with what i suspect has a grub screw in it.

any help would be apprectiated. thanks.

Interesting. When I swapped out my crab distributor for an earlier helmet style distributor, I ended up swapping the cam covers. I can’t imagine an adapter plate being able to do that. Here’s some pics of both. Can’t see where there would be a third mounting location for the adapter plate.

Have you removed the vacuum line?

i discovered, after i found pic of the plate in an advertisement that what i was looking at and assumed was probably some sort of grub screw, was actually a threaded hole that from what i could see served no purpose. and i still have no idea why it's there.

and so i began to take a closer look at the plate and after a bit of prodding and feeling around and with the help of a mirror, i found there was a third screw there, just like the other two, all the time! imagine that...

it was the pic that made the difference.
