Inside distributor question

[GnrLee01]

Am I missing a small bolt here? It's not inside, and I'm not sure if there was one there ever, but I'm having some rpm signal issues....hooking up holley sniper 2, and rp

m signal isn't clean.
Hard starts, so finding extra items that needed to be fixed, but wasn't expecting this.
I will fix the gap between pickup and rotor, but this piece moves around alot, seems there should be a screw in the top hole.

Nothing goes in the indicated spot on the pictured plate in the single pickup application. It can be ignored in this case.

More information

The area and holes at that spot allows a second pickup to be mounted. Earlier production plates did not have this extra area and looked like the following:

The later production plate with the extra area/holes can be used in dual pickup applications that use the dual Start and Run pickups with vacuum and mechanical advance but without Electronic Lean Burn or Electronic Spark Advance. The extra holes are for the mount and adjustment of the second pickup.

The dual pickup applications that use the dual Start and Run pickups with vacuum and mechanical advance looks like the following:

The connection for the dual Start and Run pickups is as follows:

Dual pickups that use the dual Start and Run setup without vacuum or mechanical advance in Electronic Lean Burn or Electronic Spark Advance have a solid plate with no advance capability and looks like the following image:

The following image shows an Electronic Lean Burn or Electronic Spark Advance distributor with no mechanical advance, nor vacuum advance:

Thank yall for the replies!

I have also discovered that the vacuum advance plate will trunk, but hangs up when it tries to return to its original position. I can twist it with some pressure, as it snaps past something that it's hanging up on, so I'll be disassembling it tomorrow to see what it is hanging up on.

Then onto voltage tests with coil, ballast resistor, and orange ignition box rests.

That toothed wheel look too low to yall? Should I pull this thing up some to get more signal strength to the pickup?

Found sticking problem, the vac canister rod was slightly twisted, in a bind at full release, so we straightened it out, problem gone.
