And it's fifty years old! I put fresh rubber parts in mine, all in all, around a $1000 worth. I'll add, mostly front and rear glass, once pulled, then the old seals, usually find a good deal of rust at those seams. Better to deal with now, than later.
Hint. If you try to pull the glass. Hit the rubber seal with a good coat of WD40, and let it soak. It helps to soften the rubber. To take the window out (in one piece), go by how the service manual tells you. Get one of the nylon wedge 'tools', that's used to get between the glass, and rubber seal. Go slow! That's how the glass is forced out of the rubber groove it sits in. Opposite to put the window in, with a new seal.
Both front and rear glass, bottom corners are the critical areas, easy to break.
Once I dolled up the front/rear window seams, I put a line of window sealer into the seals groove, that fits into the metal seam. Work it all into place. Then, I installed my glass, only using lightly soaped water (helps it to slip), and glass goes in with no sealer. Once in place, rubber groove does all the sealing. Mine is dry.
