To do list (where to buy)

[62 Barnfind]

The test drive yesterday made me a longer todo list. It really told me that this truck spent it's whole life as a farm truck. Nothing seems to work or worn out. I'm going to have to do the complete brake job, lights, seat cover, horn and turn signals. I have read that some people were having trouble in finding the right brake drums. Is this still a problem? I also was looking up the horn parts in the steering wheel. LMC only showed two of the parts, Classic did the same. My horn stays on all the time. I have all the pieces and I cant seem to get it to work right. Anybody had the same problem and where do you get the parts from? Any help would be great!
