@Malleus I did a bunch of research on the same topic but, after looking for 15-20 min, I can't find record of my order or a partial tube of what I used. I do remember being able to find an acceptable substitute (though I know that's not much help to you).
Regarding installation - you can certainly do it yourself with a helper. I hired an old school guy who knew how to install using a rope to pull the inner lip of the gasket from the inside and I helped / made sure he followed the instructions from the FSM religiously. Knock on wood, no leaks.
I think did the back glass myself using the same method and sealant with the same result. My wife helped and we are still married so that should tell you the level of effort required.
