Installing top weather seal

I have a question my car when i got it was a half assembled from a previous restore so it has been difficult putting back together it has been a big guessing game. My question is I'm installing the top weather stripping and i have all different type of screws and wandering which ones are correct and want to know if i need to pick up more corn nuts. I noticed when i took the the top frame apart some screws had corn nuts on top of them and others didn't. So i want to know if every screw needs a corn nut on top of it to protect the top? I have pictures of the hodgepodge mess of screws any advice would be helpful.
