WANTED: '76 Sceptre Windshield Latches

[ChrisG]

I just purchased this Seacraft at auction and I'm trying to get it in the water for the season. All of the windshield latches are cracked or broken & I'd like to replace them. These are the small black plastic knobs with a ring to pull down on. You twist the knob to lock the windshield in place. Does anyone have any ideas of where I could locate about 10 of these? West Marine & Boat U.S. didn't have a clue. Thanks for any info you might have.
