Help finding windshield grab rail 18’

[Bandit91]

I purchased a 1975 18’ seacraft earlier this year. The boat was well maintained by previous owner but I’ve been working out little things this summer. One issue is that someone removed the grab bar around the windshield. I would really like to have one and was wondering if anyone could give me ideas on where to locate one? The boat has the original console and I’d be glad to measure it if anybody thinks they have one laying around I could purchase.
Thanks,
Ryan
