Windshield Gasket

Hi, I need some help.

I need a windshield gasket for me 1974 Dart 4 door sedan.

The last time I bought a new windshield I gave them a gasket I bought for my 2 door and they couldn't get it to work.

Does anybody know if there is any difference between the 2 door and 4 door gaskets?

The sellers on Ebay are listing the gasket as for a 2 and 4 door.

I would appreciate any help.

Thanks

Miguel
