The gold “nuts” as you describe them should not remain inside the machine. Those are the keyboard mounts and should have be removed when the keyboard was removed. They should have remained inside the keyboard itself.

The motherboards arrive with only Shopfloor diags on them. The SHIM build instructions don’t seem to work. Finding the process to complete the new installation after the hardware component seems to be impossible.
