Call Atlanta Marine and ask for Tony. He did mine. He drilled some holes, I can measure where if you like, on the inside of the tower tubes. He then inserted the captured fasteners, then bolted the top frame up using the L brackets and 2"x1/4-20 bolts. Use wingnuts if you need to take it down often. He strung the tramp top with wire ties first, enough on each side to hole the cloth while he laced it. I used 1/8" nylon twine to redo mine last year.
There are pics on the TMS Parts lookup page, search for tower.
