Thanks for the welcome and the advice!
I've climbed in the drivers window, and after lubing up both doors I spent some time checking it out on the inside to get a feel for what I was getting myself into.
The clutch pedal actuates and feels like it is working fine, the right side of the shaft rubs against the floor pan a bit making a squeak sound, but thats easy to fix.
With the clutch depressed, I ran thru the gears, and much to my delight it feels nice and tight, and slides into each gear with a definitive 'click'. The shift lever has a smaller lever that looks like it is designed to be actuated by a finger. Possibly for a two speed axle?
Steering wheel is free and turns the front wheels as well as you'd expect them to, considering the truck is sitting in the middle of a frozen cow pasture.
Ignition key still hanging out of the ignition, and it turns.. altho after nearly 30 years of sitting, the battery is obviously dead.
Sitting in the driver side, tward the bottom of the dashboard on the left there are two controls for the heater, that appear to be made of Bake Lite. The right most control actuates freely, the left most control is frozen.
The hand crank for opening the windshield is pretty tough to turn.. I got the windshield to pop open about a half inch, then cranked her closed. No doubt i'm going to be on the WD40 prefferred customer list before this project is finished.
My local autoparts store looked at me like I was from another planet when I asked if they had a Chilton manual for a 1946 Chevrolet 1 1/2 ton truck, so if someone can reccomend a good place to score a service manual for this truck, it would be greatly apprecated.
I found a copy of the 1942-1947 Chevrolet Shop Manual online, but it dosen't seem to cover anything but automobiles. I've also found a dozen or more websites willing to sell a CD-ROM with the '42-'48 Chevy Shop Manual on it for $50 plus $4.00 shipping.. but if that's the same as the one I found free online, it isn't going to do me any good.
I'm headed over there this afternoon to snap some pictures and see if the trucks WD40 bath made any headway in freeing up that door.
