Joe, visit some of the marinas and boat yards in your area.
sometimes they remove all the hardware from the old boats
they take in as tradeins or abandonments before they scrap them.
They may have a coffee can of clips & brackets in the back room.
I need 6 that hold down the center part of the windshield
for myself but I will make them out of 3/4" aluminum flatbar.
Luckily, I have the corner brackets.
if you find something that works, please come share it with us.
I will probably never buy another boat
