Does BCB or anyone know the size and length of rivets holding a boarding ladder to the transom on a 2003 P3? I noticed last night that one of the rivets is broken, and the others are loose. The top seemed solid still. I didnt get s chance to look in the bilge to see if there is any type of backing plate. From the outside, it looks like just the rivets and some marine silicone to seal. No epoxy. Can anyone comment on that topic as well. Im half thinking about bolting it if I can get inside to reach the nuts. Thank you, Bill
