Need advice resealing an A.R.E. camper shell

I have a used ARE shell that has no ID tags other than one ARE logo on the side.. I'm fairly certain it's the mx series.

Anyway I've got a couple leaks that are apparent when it rains and I dont know how these windows are secured in and what product I should use to reseal them. The top 'moonroof' type window is the worst (those are the first pictures) hopefully some of you guys might steer me in the right direction for replacement seals or maybe a link to a thread where someone has already DIY refurbishing the topper themselves?



These are the mounts for the front/top moonroof type window


Where it's leaking through one of those mounts



Some sort of pressed in seal? It's for the side slider and I hope I can order a roll of it to replace



This is the fixed portion of the side window.. I cant tell if that's another roll type seal or if it's a black squeeze caulk type sealant that's just pulling away due to age?



This is the lowest rivet on the back flip up glass frame above the tailgate.. I cant see where it comes through on the inside, can it be drilled out and replaced with a bolt?


Thanks for looking and offering any suggestions
