The seal should be butyl. Fairly easy to cut out with some piano wire or a removal tool if you're careful - a removal tool can do as much damage as a hammer if you're not paying attention.Wrecker sounds plausible, I didn't think those hooks would fit in those little holes.
I'll try cutting the back before I call in the pro, probably save over 100 if I don't break it!
Helpful hint: butyl tends to be gummy, even if it's 40+ years old. The colder weather makes it less so, but a little oil as you cut keeps it from re-sticking.
Rear glass, being tempered, is much easier to work with. It can flex a surprising amount, unlike the laminated front glass.
