I've been poking away on this thing, mostly collecting parts and re-assembling it after the fab work.
Got some new, aftermarket seatbelts for "Toyota pickup" off eBay, they came with nice metric hardware and went in with minamal fuss. The originals were roached.
Some rust prevention, converter work.
Made some nice, heavy battery cables and got it to a point where I want to drive it around a bit.
Lots of crank crank crank, some sputtering and running, but nothing consistent. Went ahead and yanked the carb, got a parts store rebuld kit, am just finishing that up. I didn't do a very thorough job of it the first time around a few years back.
Also found a repop replica carb on eBay for $86 shipped. I'll report back on my findings.
Neet sticker on the side of the air cleaner: Mr. T recommends 10000mi between oil change even with dino oil back in '81.
The secret is to keep it wet for awhile - which works better with the liquid and a foam brush (or old/cheap paintbrush). Knock the loose stuff off with a wire brush and then slather it with the rust remover. Then have something else to work on and just keep slopping some converter on there every now and then until it looks good to you.
