Just picked up a '77 Glassmaster tri-hull from a buddy of mine, going to resto the boat up to standard but I can't for the life of me figure the model number of the boat. The only number I can figure is the serial number on the data plate, which is 326005XD. As many of you know glassmasters are tricky to find parts for and not knowing the model number makes it even harder to figure. Any help from the glass gurus would be greatly appreciated!! Just joined the forum, so not sure if I can post pics but I'm going to try so I can make ID easier.
