I had the boat measured by the boat shop who will do the tank. We settled on 72X27X9" tank. If I did my math right, that will give me 75 3/4 gallons. That way the tank can be slid back into the tunnel w/o a hassle and then tied down. The fabrication shop here locally is about 2-3 weeks out so it will be toward the last week of May for the tank.
As far as the holes are concerned, they will do a little grinding of the bulk fiberglass that was used to hold the deck in solid and then glass a strip under the flange to have solid holes for the screws.
