Just replying because nobody else has. I guess the "turtle deck" name made sense on the T up through '25 but for the '26 & '27 there was the rounded deck lid you have. In '28 that became higher and was either a rumble seat lid or a trunk lid. About a year ago there was an article in Street Rod Builder about a new '32 body in steel that allows a flap around the back of the seat to lift up and hide the top bows and top there after folding down. Do you have a fiberglass body or a steel body with a welded door? Speedway Motors here in the U.S.has a door kit for a fiberglass body to saw out the passenger side and add one door for entry/exit. What you are asking sounds possible to me but ONLY after a LOT of trial and error bending aluminum tubing with motorboat fittings. I think you could get it the way you want to fold down behind the rear of the seat but you might waste a lot of tubing in making your own bows. It's not impossible, but maybe if you added one door to the body you could make do with a chopped top using parts intended for a stock '27. There are some folks here on the Forum who can do almost anything in a professional way, but it would be beyond my talent and so I would add a passenger door and try to set up a regular chopped top for a '27.
