Thanks man. Yeah that tank is a tight fit but there is about 1/2" on the sides and the top and bottom have plenty of room for exspansion. I wanted to get it in there as tight as I could, so it would not move around, yet leave alittle wiggle room. Last night I put some wedges in the top of it at the front bulkhead to hold it down and also put some blocks at the rear of it under the floor supports to help hold it down. I will post pics later.
If the tank ever becomes an issue I will cut the supports out when I cut the deck up. Hopefully It will never be touched until another 20 years at least. All the other stuff held up 34 years and I think what I am putting back is even better.

Well I know the stringers support the hull from flexing and give the floor something to attach to. My comment about the floor helping hold the stringers together is basically saying it is going to add that much extra support. Like I said if this boat held up 34 years, all this extra glass is doing nothing but making it stronger. And the floor supports are cabosiled in with two layers of 1708 where ever it is glassed. There will be no foam going back in it and there is nothing but open space under the floor so she should stay well vented.
Keep the comments coming. I am always open to ideas and things that I can improve on.
