With the original rubber I would doubt it will come out in 1 piece, I suggest you locate replacement rubber then cut the old rubber to allow the glass to be removed without breaking. The glass is most likely flat and as such almost any automotive glass shop would be able to supply replacement it may not have any of the manufacturer markings on it though.

A few years ago I replaced the rubber for the rear and side fixed glass on my ‘37 coupe.

I used a utility knife to make multiple passes through the old hard rubber. I made the cuts along a line that I figured was between the edge of the glass and the pinch weld on the body. I did not try to cut very deep but just applied light pressure with each pass on the same line. After I made the first few passes I sprayed the line with Ru-Glyde as I continued to cut into the rubber. That made the knife blade slide with less friction. If I thought the blade was getting dull,I changed it right away.

After I felt like the cut was as deep as the bottom of the glass I slid a thin putty knife between the glass and rubber. Once again I sprayed that gap with Ru-Glyde as I continues to work the putty knife around the perimeter of the window. Eventually the rubber started breaking up and I could remove it completely.

Then I used the putty knife on the inside of the window to separate it from the inside rubber lip. Eventually the glass will break loose from the rubber.

I put masking tape along the body and glass to offer some protection.

Patience is key!

Ru-Glyde is a lubricant for rubber. It is often used when installing tires on rims. I also use it to clean tires and rubber floor mats as well as when installing glass. It is not harmful to paint. My local NAPA store has it.

I know some people use a strong water/dishwashing liquid mixture to install glass. Mix it about 4 to 1. That should help make the knife blade slide easier.

The reality is that with old glass like that there is a pretty good chance that at least one of the windows will break. I was able to remove all 3 of mine with no breakage but broke the rear window installing it. The local glass shop that cut the replacement told me that this so not unusual. The plastic laminate layer gets brittle over time. So the 2 sheets of glass cannot move slightly in relation to each other when you are prying them into the seal.

Several years ago a friend used the dishwasher/water mix when installing his windshield. First rain he encountered resulted in what looked like Lawrence Welk's bubble machine going down the road. We all had a good laugh over that one.
