Probably
Actually a side view of the bolts probably would have been more helpful. anyway from the looks of the pic the top bolt is your stop bolt, to keep the keel from going any further in its travel, and the bottom is your pivot bolt. Now as I said a side shot would have been better to tell. Your lock down bolt, should be forward of your pivot bolt and up a little from it! but cant tell with your pic. As to your cockpit, well apparently the previous owner put something in those holes, maybe vents or something, but it should just be white fiberglass like the rest of the cockpit! You can fix that yourself very easily! Anyway good luck with your project! With the interior stripped out, you can make her the way you want!
