Today I got farther along on the disassembly of the cab, on both sides of the firewall. I pulled the vent cowl off, the wiper motor, heater core, front window, and the glovebox. I am really amazed by how little rust there is around the window. Being raised in Ontario where salt and humid weather eats everything, I'm used to seeing more rust after 5 years of existence, not 50.

One other major difference living here in Colorado vs. Ontario is that every piece of rubber and plastic is dried out until it's ROCK hard. I don't remember that happening the same way on dad's old projects. When I pulled the rubber gasket from around the windshield it came out in small hard chunks almost like a piece of bondo or dried clay.
