I recently removed the front bench seat and backrest/ bunk bed out of my 1974 13' Boler
and replaced them with a front dinette. They are free to anyone who wants them. The fiberglass bench seat is in good condition and I assume the backrest/ bunk is too, although I would never sleep on it.
Since these are big items I assume shipping will be quite pricy. Local pickup or delivery in the Calgary area would probably work best.
If there is interest I will forward or post pictures.
