The steel seatpost and seat has got to go. Does anyone know what diameter seat post would fit? The bike I estimate was made in the early 80's.

Take the old post out and near the bottom were the minimum insertion line is will be the size, a 3 digit number like 26.8 or 27.2 and that will be the size. If unmarked then use a set of calipers to get the size or most lbs have a tool to measure the frames seat tube forthe ID of tube.
