ARE DCU cap window repair help

I have the are dcu cap on my tacoma i bought used in the summer and noticed water leaking from window frame in the front and back of the camper. Looks like sheet metal screws around the frame and pops out but before i get deep into it, anyone know if it’s easy to take out and put new seal in? It’s not a big deal since it’s currently used for work would like to get it fixed in the spring when the weather is a bit nicer to work with

 

Pics might help but it should not be too hard. It will be a little sticky after years in the same spot. New window gaskets are literally everywhere.

I’ll get pics in the morning, still at work and dark out

 

It just started raining so no leaks right now but closer look at the gasket seal it’s like the thick tar rubber sealant we call dum dum if that’s the correct term. So gonna have a lot of fun getting that glass out to reseal but the second closer pic shows the white spot is where water leaks in from

 

Well it's not bad for sure. I'd take your time and use a heat gun if you have to. That will help loosen up the tar or sealer. Plan on a full day and if you finish early, PARTY...lol.
looks like a flange type seal. this is just a quick search.
