replacing insulation?

I have 74 31' AS that I am restoring. Is it necessary to replace the insulation. I haven't determined yet if there is water damaga. If there isn't, is it still a good idea to replace it. Also, how do I remove the rivets and when I put the skins back on, I am assuming I should use new rivets and so what will I need to punch those new rivets in? Thanks!

After you see your insulation, it might help you make up your mind. Ours had lots of mousie tunnels...

Even if clean and dry, I would upgrade ~ you don't want to take the skins apart again, do you?

We tried a combination of materials and did a sandwich layer...not sure how it will fair out. Seems pretty good so far. I think on one thread the guys said they would all get together in 40 years and reinspect to see who was right!
