I pulled the truck out to get it started and tuned, and I witnessed the slow, painful death of the electronic pickup inside the distributor. It barely ran at first, then it spit and sputtered and backfired, and right after I pulled the coil wire off the cap and tested the spark (thin and yellow, btw) it stopped sparking completely.
I pulled the pickup out of the distributor and tested it, multi-meter reads about 3 million ohms... It's dead. New one is about $75-$100, but I did find a cheapo chinese knockoff for $15. I figure if it doesn't work, I'm only out $15.
My other option is to buy the MSD magnetic pickup for $28, but I'd have to grind it in a few places to make it fit the distributor. The reason for this is to be able to use a MSD 6A digital box and have all of the mpgs and horsepowers. But it's pretty involved and will require a lot of very careful cutting, drilling and grinding to make it fit and function. I don't know if there is a different pickup that will fit and still trigger the MSD box, but I'm still looking and doing research. It's unlikely that I'll try this right now. But it's an option.
On another note, I pulled apart the wiper motor and found about half a pound of grease, scored and slightly burnt brush contacts, and one of the magnets inside the housing had separated from the housing and was stuck to the motor armature itself. Some epoxy to keep the magnet where it belongs, some 600 grit sandpaper to clean up the contact surfaces, and I'll have a rebuilt wiper motor. Still not sure what grease I want to put in it, but the crap that had been packed into it was yellow and smelled terrible. I might paint the housing, depends on when I get around to putting it back together.
And finally, I pulled the 2WD parking cable off and put the correct length 4WD parking brake cable on. Now that the lever underneath the truck has full range of motion, it kinda sticks a little bit right at the end. I just need to take the lever assembly apart, clean all the rust off the pins and moving parts, lube it and put it back together.
But the parking brake does keep the truck from rolling now, when it wouldn't before.
