You mean the coaming in the cockpit, right? I made my own, using the old trim trim as a pattern. The only painful part was getting the curves right (and matching) on either end; I used an electric scrollsaw to do this. Wasted some wood as I messed a couple up! It was not a difficult job. Anybody with a rudimentary woodshop could make it in a couple of hours, probably less. But teak is expen$ive.
I could probably trace the pattern and sent it to you if you would like (sadly, right now I don't have any time to make any!!). If you had the inclination, you could get the teak cut and then make the corners yourself using a manual scrollsaw. The original coaming used a simple butt joint to connect the curved ends to the straight strips; you can get fancy there if you wish. Another area to get fancy is to rabett the straight pieces so they curve over - and conceal - the fiberglass.
