Reading some posts I find the vent window frame is not reproduced, but the glass is available. What is the best way to get the glass out of the frame without damaging it?

The best I can tell the door glass run is held at the bottom by rivets. Is this right? Pictures in the catalog (LMC) do not show any kind of fastening at the bottom of the run.

Is it better to get a repro division bar or have the original plated?

And the window lift channel. Better to get a new one or try to get the glass out of the original?
