Quick update. Looking at it right now.
I think PSA left fillets on the rear lug and they are resting on the lower and not allowing the hole to be low enough. I can see the hole is a little too high in the rear with the front pin in.
Can't measure very precisely as I dont have a gage pin and only a set of punches and calipers, but the rest of the dims seem about the same.

Thoughts?
