possible alternate
Dave,I had a similar problem on our 1977 H-33. I considered getting replacement matching teak and holly plywood ($100 for a 4X8 sheet steve..at least here on the East Coast). I decided if I didn't do the entire floor, it would probably look funney as a new sheet will not look anything like my old 23 year old floor. I decided to try a different approach and not try to match the existing floor. I tore up the bad section of flooring and replaced it with a new piece of plywood which I then covered with a piece of linolium. Take a look in the photo forum. You'll have to do a search for "easy floor fix", or try the link below
