DC - the fuel tank is in the center, between the stringers. Your t-top will mount on the outside of the console, which will be outside the stringers. You will not be able to reach where the screws come through outside the stringers, as the deck sits on top of the stringers. And the area outside the stringers is filled with foam. Running screws through the deck without backing plates and using 5200 to glue the base to the deck may be your best option...
