Hi Fumblin46!
You've come to the right place to find out about your truck. 'Welcome'
Sounds like you're going to have fun with that 1 1/2 ton!! I have a two ton so know a little about some of things you are mentioning.
Don't force the windshield crank too hard. You'll find that there is a kind of worm gear on the crank that engages a curved metal piece that has slots in it. The gear moves that metal piece back and forth and forcing it could ruin the slots. You'll find a way to loosen it up though.
When you get around to greasing the truck you'll find a couple of nipples on the shaft that the clutch and brake pedals are attached to. My clutch pedal rubbed on the floor pan too but it hasn't since it was greased on the shaft.
Most of the supply companies you can link to, from here, should have reproductions of the GM 'Chevrolet Shop Manual--Cars and Trucks'. Check out their on line catalouges.
Good Luck.
George
