Progress this weekend: removed the old Weber carb, began removing the old front blinkers to replace with new ones. Replaced the headlights with OEM for now. Hope to upgrade to LED or HID in the future.
Does the 40 have a high beam switch stock?

Removed the fuel tank (plastic - hmmm) and the fuel collector (also plastic). Floor was not too bad under it. Looks worse from below.

Then hosed out the inside of the truck to get all the caked on dust and grime that coated it. Came out a lot cleaner.
Worked on the drivers floor board. It was coated with something that was thick (maybe 1/4") and black, maybe POR15 that I read so much about? I chiseled it out with a big screwdriver and a hammer.

It came off in brittle chunks. Floor was virgin under it!
This morning, decided to punt on the idea of finding an inexpensive OEM booster rebuild, and went to the PullAPart for the first time. Pulled a 1995 Camry booster in about 25 minutes [EDIT - does not fit, too new!]. Pretty cool place. Felt like a criminal walking around looking inside all the cars. Very clean booster and valve for $28. Still has clear grease on the spindle. They even put little deodorize in in all the cars. I didn't even get my khakis (too) dirty.
Have about $500 in parts sitting in the SOR cart at the moment. About to pull the trigger. Getting the transfer case small parts kit, plus the additions 2-3 gaskets they said "get if needed". How the h*ll do I know if I need them until I get in the middle of this? Since they were cheap, I went ahead.
I'll tell ya, this intimidates the cr@p out of me. I've never done transmission work, and I'm kinda dreading it.
Also included is new voltage regulator, emblems and pads for the rear, new door panels (doors are from the same donor truck that gave the hood evidently). The more I dig, the more I learn.
I'm to the point now where I can begin to put the engine bay stuff back together again. Once water pump arrives, I'll put it back together. I'll work on the transfer case gaskets and bearings, fix the eBrake pads that are soaked (kit in hand already), then radiator, hoses, belt, etc.
Need to get mirrors, replace blinker flasher units, and then, hopefully, take it to go thru (fail) emissions, and get the title transferred!
Then the real work begins, but that can wait a while.
Thoughts?
Oh, burning question - the hood is structurally weak when lifted from one corner. The central brace that runs from back to front is not connected. Is the supposed to be spot welded? I see no welds or bolts in it.
