Philip....The rubber used to secure the rear windows is an 'H' section and are not designed to 'string in'
These are designed to fit to the body and then the glass is worked into the rubber using plastic spatula or similar.
The type of rubber that is strung in is an 'S' section and behaves in an entirely different way.
As Tim said the tricky part is fitting the lock strip.There is a tool that makes this sooooo much easier!
This subject has been covered many times in the forum.
I'm sorry I can't go into too much detail at the moment as I'm getting ready for work,but I'll try and hook up later and guide you through!
