I'm in the process of restoring a 1946 Higgins runabout. I will soon be looking for some parts for the boat. Also would like to as someone with experience in restoring these boats.
When you have a question, submit a post with that question. Just ask it and folks will answer. I'd caution trying to isolate to a single person or boat. Most stuff is going to be generic boat, or wood boat related. You'll find very little being Higgins specific. Don't paint yourself in a corner trying to have a side conversion with one person about Higgins.
In short, just ask the questions you need answers to. Don't worry about who is going to answer.
