I replaced that front windshield on my 1991 Passage 42 in 2001. I dealt with Hunter, who informed me that although they owned the casting for that windshield, they had contracted out the manufacture. They put me in touch with the outfit and I ordered directly from the manufacturer. At the time I was also in San Diego (Harbor Island), and I had it shipped overland from Florida. It arrived in a HUGE crate on the back of an 18 wheeler. The product was perfect--identical to the original. If you intend to continue with your replacement, you might start by contacting Hunter for that manufacturer information. I'd search my receipts for you, but I can't get to my boat (due to the level 4 lockdown here in New Zealand). I ought to be able to get back to my boat in a month or so, however. Let me know if you'd still like that name.
Good luck,
Paul
