Bill in response to your question about the blind frame on my TDB, I made it myself. I took four thru the haul nylon fitting and drilled the center out to 3/4 of an inch, I than drilled the deck in four corners and screwed and epoxied them in place. I bought four post that are used on mounting a seat for a bass boat. The front ones were 11 1/2 inches high and the back ones were 13 1/2. I than bought 3/4 inch ( If I were doing it again I would use 1 inch ) aluminum tubing the length and width I needed and connected them using nylon bimini fittings . Two people could set it up in minutes. See attachment dated Oct. 22. Sorry I forgot one item. On top of the post I put 3/4 inch solid aluminum shaft in order to attach the bimini fitting.
