Alright... little update. Finished off the brakes and the truck is back on the road. Man, it's hard to find time to do anything with 2 kids under 4 yr old. But, we were able to get things done this weekend. Basically, all new front brakes - new rotors, pads, brake lines. I kept the calipers, but there's a fitment issue with those - see this thread:

Jumped on the rear brakes and rebuilt those. New springs, new shoes, new cylinders. I think I still need to do a little work on the rear brakes. I had a hard time getting any fluid to come out, hardly a drop, if any at all. I think I'll try and replace the rubber brake line back there and see if that helps. It's my first time messing with drum brakes, so that was a learning curve. But, it's not too bad once you know what's going on back there.
Took it out for a test drive and the truck stops just fine, now. No wobbles, doesn't pull to one side or the other! I'm excited to get it back on the road again!
