Rob, My header tank, like yours was a pretty poor fit. Also the "flange" was basically "rolled" off the header tank so that even if it fit properly, it would make contact with the fwd deck only on one thin line. I had very little confidence in the structural integrety of the tank-deck assembly. If you're going to use the fwd hinged canopy this assembly is especially critical. Here's what I did. Cut the entire "flange" off of the tank. Sand the top inch or so of the tank, inside and out. Marked a 2" wide line on the deck around the perimiter of the tank. Covered the bottom (tank side) of the deck with plastic release tape. Lay 2 bid, 2 inch wide tapes over the line. Lay the tank on the deck. Put 2 bid tapes around the perimiter of the tank 1/2 on the tank and 1/2 on the deck. Let cure. Pop the tank off the deck and you have a perfectly fitting, wide, cap strip like flange. Build a micro fillet on the inside and lay more 2 bid tapes around the interrior side of the tank and let cure. Hysol the tank on the deck with a strong, perfectly fitting, 2 inch wide flange. Its probably overkill but I know that it's never going to seperate and may even be lighter than glopping flox in to fill the huge voids. I have pictures of the entire process, let me know if you'd like them.
