I have a 1990 Ultra Custom Boats 21 open bow. The windshield is held in place with several small bolts with a black plastic cap on the outside and a SS acorn type nut on the inside. While at lake Mojave this weekend, I noticed that one of the fasteners was missing. I have tried endlessly to find this type of fastener on the internet but have had no luck. If anyone know where to find these type of fasteners please let me know.
Thanks in advance for any help.
