Lugnuts sounds like your man. Make contact. He has a 65 C10.
I have a 60 GMC.
Anytime you encounter someone who is having a bad day or you just don't communicate with, it's best to move on. Trying to get parts that you don't really know what you need would be difficult on the phone. Mail order junk yard parts is not a good idea. It's a recipe for a mix-up.
You won't get your parts by asking for "bits and pieces" for your ebrake. Figure out what you need and the proper names and go looking for them. Ask here if you don't know the names. The brake system/park system is fairly simple. Some may be available at a auto parts store. As you know, basically, you pull on a lever and thru rods, brackets, clevis, cables you end up pulling on the two cables equally. I don't know what you know so...I would find an actual 64, crawl under, take a bunch of pics. Take pics under dash and then find the parts. Books, internet and blogging are good for part names and advice but no substitute for an actual truck to study. That is what I would do FWIW.
If you see looking for parts as a waste of time/PITA, instead of fun, you and I are different on that point.
It's good you have the cables and the drum hardware. After you see what all rods and cables you need, you may find some guides and such are still on your truck. PO probably had an interference problem with motor/tranny swap. Don't see why he removed the under dash handle/lever.
