Windshield Chrome Beading

[70GMCer]

Thanks for all the help that has gone my way as I am still learning about these "Square Bodies".

Want to ask about a 67 to 72, I can mostly answer that. But still learning these trucks.

Anyway, I'm going to have to replace the windshield on my 83. It has that chrome beading that will need replaced also.

Here's my question.....Does that chrome beading have to be installed onto the rubber before installing on the windshield?

Or, can I install that after the windshield has been installed?

I also think that there is 2 different style rubber gaskets. One w/chrome beading & one without the chrome. Is that right?

(Ok, more than 1 question)

Thanks again for all the help....
