Thanks for all replies.
I tried putting the rubber in the opening first with ones that I had bought from JC but, the rubber was too stiff and was impossible to fit so we gave up the notion in frustration.
We ordered another set from Steele Rubber and it was much better although we ruined that set trying to once again fit the glass into the opening.
After reading this and many other threads and talking to Steele Rubber I have decided to put the new set of rubbers on the glass for a week or so to climatize and then fit them in the opening. Steele suggesting leaving a little slack and then gluing the two ends together. This is consistent with the methods suggested for the other windows in the truck.
If it is still warm enough here this year when I get the new rubbers I will try it and report back.
This is quickly becoming one of the most challenging tasks of my rebuild - one that I thought would be easy peasy. How on earth did they ever do this on an assembly line??
Thanks for all your suggestions.
