I saw this thread yesterday but didn't think I could add anything relevant as fillet says his tank is next to the helm -- mine is aft of that, so I don't know how they compare. Dimensions are complicated, as the bottom of the tank is V-shaped but flat on the bottom, kind of like this: \_/ I'm sure I still have the sketch with dimensions somewhere around here, so Fillet, if you have access to a fax I could fax it to you.
Florida Marine Tanks has specs on old Wellcraft tanks (so I understand) and can make a new one out of aluminum for you. I had a plastic tank built to same dimensions by Triple "M" Plastic Products in Kennebunk, Maine for about the same price quoted by Florida Marine for aluminum. It's foamed in and will probably outlast both me and the boat! :)
