Anybody know if glass is different for a 4 door?

Thanks guys,
Guess we're gonna have to get on search for a 4 door, somewhere near SW Ohio, to take apart. We bought the window rubber from a vendor at the Nationals and according to this vendor, the rubber is all the same, from 70 to 76, 2,4, they said it, " doesn't matter how many doors it has". Hope the window seals are even usable?!!!
