I built my own racks for a fiberglass top, however, it wasn't a very valuable top. It was simply 2x4s raised 2 1/2" by ABS posts. I cut 4ea 2" thick rings out of 3" ABS, and recessed these into the wide aspect of a 2"x4", and counter sunk a 1" paddle bit about 3/8" of an inch on the opposite side. I then marked and drilled corresponding holes in the canopy, and placed a 3/8 plywood backer inside, about 3"x3", and ran 5" long 3/8" pan head bolts all the way through to suck it together tightly. The recess in the 2x4 allowed the pipe to slip in and leave no reveal, so it was self-leveling to some degree. I didn't have to seal it, and it never leaked. It looked a little countrified, but painted it was hardly noticeable, and worked perfectly for a couple years, till I got rid of the canopy. Total cost out of pocket? 0$
