Refitting MK1 Escort windows

I fit load of windows back in the day and we never used anything. just get some strong cord and put it between the gap in the rubber all the way around the window, overlapping around 30cm. Get a mate to help you place the window in the gap and get him to put gentle pressure on the screen. Now when you pull the cord from the inside it will pull the rubber into place over the metal lip. if it's not you need more pressure on the glass. this is a safe way of doing it.
check for leaks, if the bodywork is good you should be fine, but you can always squirt some sealer under the rubber later if need be. Hope this helps.

Thanks,
Thats pretty much what I thought. Maybe a litle mastic especially inthe lower corners of the front and back windows.
I might have a little practice with the old rubber seals for fun.
