Bryan, the best thing to do is to call a local auto glass shop.  They
can pop the old window out, check out the frame for you, and pop the new
seal in and it doesn't take them any time or extra effort.  I would say
the cost should be under $100.  Actually I have gotten a brand new
windshield installed for around $220.  With an old windshield there are
no guarantees that it won't break when trying to either pull it out or
put it back, but at least a window shop guy has a good chance of popping
the old one out and putting it back in one piece.  Just my experience.
