I'm looking for a bolt that connects the brake pedal to the brake booster linkage. The truck is a 1979 F250, 400 engine, 4x4, automatic. See the pictures below for a visual of what I'm looking for. I'm trying to connect the part in picture 1 (the end link of the brake booster linkage) to the part in picture 2 (the bolt hole connected to the brake pedal).
It seems like it needs to be a special bolt, so I'm not yet willing to just pick up any nut/bolt at a hardware store and slap it on. I don't exactly want my brakes failing on me!
