Welcome to me. (I think this is my first post) I am just beginning my project on my '73 23'. The cockpit windows have apparently leaked for a long time, rotting out the outside edge of the cockpit floor, on both sides. (I'm still working on sealing the leaks. Just ordered some new JimB cockpit windows from JimK). So in order to replace the floor boards, I have to remove the seat bases. I see that they are bolted down through the aluminum framing, with a free nut on the bottom side. And on the outside edge, there is only about an inch between the flooring and the wheel-well. So since the floor is already destroyed, I'll be able to break through to get some kind of wrench under those nuts to get them off. But I can't think of anyway to reach back under there to secure the seat bases back down once I have my new floor in place. How have others done this before?
I'm considering sticking the bolt up from the bottom, secured with a nut just above the aluminum frame (with corresponding hole drilled in under-side of plywood), secured with a nut on top. But that will probably leave some bolt sticking up higher than the nut. Your thoughts?
While I'm here, what do I need to know about the replacement plywood? Does the underside need to be treated with anything to endure its exposure to oil and water, etc?
