I had a local CUCV contact come over yesterday and lo and behold - his door key unlocked my truck. Awesome. Not only that, the spare key inside the truck was an ignition key, not a door key, so I'm good there too. Key problem solved!
Also, I fixed the threads on the alternator rotor and finally got it back together. The special M18x1.25 die I ordered hasn't even shipped yet, and I simply couldn't wait around on it another week or however long it would take, so I borrowed a friend's thread file and fixed the threads that way. The nut was salvageable, so I managed to get it threaded back on there and tight. So now, that rebuilt alternator has fantastic output. But the other one isn't doing so well, so it looks like I'll have to rebuild number two. No biggie. Next payday, I'll be ordering another rebuild kit, and we'll be good to go. I know exactly what NOT to do this time, hah!
It was very satisfying to drive the beast again.
