Could these slight differences be the cause of my issue? Yes, I know...there is one way to find out, but was looking for input.

That hole in the plate will affect it, also check the throttle body flange at the IAC opening, some TB versions have no cutout for it on the flange.
You can just swap the plates with it on the car iirc, but I would take the whole unit off and inspect it.
