How to replace window glass

[56servi]

I just bought a 1931 Fordor Slant Window that was in a garage fire. All the glass is cracked/broken from the heat & needs to be replaced. I got the winshield & frame out and am now trying to get the door glass out. I started with the drivers door & have the molding & interior panel off. How do I get the glass out? It looks like it will only come out from the top of the door thru the window opening. I have the side tracks/runners loose at the window opening.
Does the glass come out of the track at the bottom & then out thru the opening or does the whole window regulator come out with the glass?

Thanks
