Lotshorses,
welcome to the Stovebolt. You have come to the right place to get help with your truck. The one thing that is very hard to find for the brake system is brake drums. If yours will clean up within spec then they wouldn't be an issue. Wheel cylinders and shoes can all be rebuilt. I kept mine original style except I changed out the rearend gears for the 4.10 set and I can go 60 mph in comfort. I think you have a fun project on your hands.
