Greetings folks, I'm restoring a 26' Shamrock Mackinaw that was basically a boat in a box. The owners ex- friend disassembled everything held in with a fastener and put it in a shed and it sat for about 9 years No need to go into all the details, but I'm wondering if there is an OEM source for the adjustabke windshield arms. There are some that are close at West Marine, but not exact where I'd need to drill an extra hole. Suggestions? Pete in Annapolis.
