1963 Dodge Dart 270 Convertible for the Wife

Beautiful, absolutely beautiful car. I do have a question about the glass install. It appears you installed the rubber to the frame first. Did you install the glass into the rubber after or remove the rubber and put it around the glass and then put it back in? The only way I have ever done it is the latter, place it around the glass, put a piece of twine in the channel and use lots of soap and pull the string out of the channel to bring the lip of the rubber seal in. Just curious as if you installed rubber to the frame first, does it make the glass install any easier? Thanks
