Yes, the rivets should drill out like any other rivet. I don't recall it being difficult to put back together, but I only replaced my bottom seal and bolts, so didn't do a full disassembly. I picked up a replacement seal from somewhere, but I'll need to dig through my parts bin to find it and see if I can determine where it came from. Not cheap, but an identical match. The bolts are t-bolts that slide into the channel and pop out through the seal. You'll need to determine the placement and punch those through the seal. If I recall, I couldn't find any stainless replacements, so I ended up using non-stainless t-bolts and just hit them with some paint. Figured they wouldn't see much exposure based on their location anyhow.
