Big John, your making good headway! I really think you've got a great looking jeep/dolly! That turned out really nice. The truck is coming along too. Take your time and enjoy the build. I find I make the best progress when I get into the mood and groove. As for windows and gaskets, I've made gaskets out of thinner styrene, and framed window cut-outs in doors and cab walls. What you do is make the gasket smaller in size, so when glued over the window opening, it frames the window, so to speak, and gives you a shoulder and an edge for the glass to sit inside.
So as not to derail your build thread, you can check out this link to see what I mean about the window gaskets and such.
