Weekend Brake job

[wpavlis]

So, my rear brakes were not working on the 68. It's been a while since I worked on drum brakes, but seeing as how this truck has 4 there is no time like the present. Everything went fine while tearing down the drivers side. I pulled these out of the wheel cylinders. Does anyone know where I can get replacements? I suppose I could soak in evaporust and paint, but I am worried the paint would wear off over time. I think they are called wheel cylinder push pins or something like that. I found some on ebay, but that's it. Thanks!
