BPS is one of the last retailers that I am aware of that has a live competent person at each store location that actually answers a phone....give them a call.....they have different Bimini dealers that can get the fabrics and parts you need for your Bimini...........
I too have dumped $$$ on both my boat and the trailer that the boat sits on........I think I may have spent more time and $$ on the trailer than the boat itself... (wheel bearings, axel, tires, leaf springs, winch, brakes, bunk-boards and master brake cylinder)
