I can't find the diameter of the hole to be cut in the inboard tank rib for the access plate. The section B-B' drawing seems to suggest that the hole should be slightly smaller than the ID of the stiffener ring. I do see that the reinforcement ring is 6-3/4" OD, but that doesn't help much.
Someone give me a clue me, please.
