Can you pull the rivets out fairly easily? Yes. The big thing is YOU HAVE to remove the castings from the hulls (at least that's the way I did it). These castings are very brittle and liable to crack when doing this procedure; my best idea is to squirt your favorite corrosion eater between the castings and the posts on the hulls, then gently pull or tap the castings of the hulls. I'm sure others have done this more than I have and have some other tips.
