Hey Jet I'm assuming you just took the piano hinge and mounted it to the transom side of the fiberglass to switch the lockerlid????
Looks great BTW, I've been working on my interior and have yet to put that hinge back for the same reason...would rather it opened into the boat, of course now I'll have to put a drain in the locker and seal off the gas tank access. I've taken the rear bench out so many times that accessing it there is better anyway!
