Re: 1978 fiberform cougar windshield
This 1978 Fiberform Cougar looks a lot like Glastron CV/CVX/GT boats. But finding a windshield that will fit & look right will be a challenge w/ the steep rake & curve. Of hand, I can't think of a Bayliner windshield that will fit, but I am definitely NOT a Bayliner windshield expert.
As hard as it may be to find, a 1978 Fiberform Cougar windshield may be your best option...
You can try some of these places, you might get lucky:
