sorry to hijack your post but if your windshield is cracked you should be able to get the seal out without damage-if you think it`s too brittle don`t use it as you don`t want a leak-i heard if you place the rubber in one of those hot water rotowash machines they come back to life like new-maybe worth a try.
one day i need to restore my 69 charger r/t and it too has the original rubber which is not brittle -i`m not wanting to save the rubber but i must save the windshield as it is in perfect condition and dated correct. what is the best way to save the windshield? cut the rubber until the windshield falls out or is there a better way that someone has tried before. i might consider restoring the car with the windshield still in place-could be another option as it is a low mile car.
all the best
frank.
