Update and appreciate everyone's help.
I found parts at the Oreilys in Fredericksburg, Va the same day I hooked up with the Old Dominion Bolters for the first part of the NDkid farewell drive.
Nice to meet some of u in person!
So far, I have been able to get the rears done.
I don't have self adjusters on my brakes so that explains why the backing up method to tighten the shoes didn't work for me. Also, one of the shoe hold down pins was missing so the shoe prolly wasn't in the right place at all. So, the reality was that the rear shoes were not really hooking up with the drums at all. I fixed all the hardware issues and adjusted the star wheel manually from the hole in the face of the drums (since my backing plates don't have holes in them-decided not to drill them out). After adjustment, the rear brakes seemed to hook up nicely while truck was jacked up. Dropped stepvan to the ground and the parking brake now works in both directions!! Making progress.
This weekends project is the front brakes. I have a feeling they are going to be way out of adjustment also.
