We need a windshield and seats to start off.
Windshields are hard to come by for old boats. Sometimes xbay or CL will have them. Sometimes a boat salvage. Sometimes a donor boat. A few here have been able to make there own, but I believe they had a frame to start with.
Seats are a personal and budget decision. Pedestal or back to back, new or used, recover what you have if you have any. I have sold several seats on CL to people fixing up old boats.
You should post some pics and show us what you have.
Also let us know the condition of the boat and what other work you are planning.
