WTB: pins to hold brake pedal linkage together on J body Mirada

The below pictured piece was behind the brake booster in my '83 Mirada, above where the brake pedal is. I'm making an assumption that this is part of the brake pedal linkage, since that's where I found it. If that is the case, then...

... I need the pins or whatever it is that holds this brake linkage together (between the pedal arm and the power booster). It looks like there must be 3 "pins" to connect the pedal arm to the booster.

And yes, I'm obtaining a factory manual, then I'll know for sure what this is, what I need, and how to do it, but for now, I know I'm missing something that I'll need to obtain!

If these are parts I can get at the local hardware store, please let me know that too!

Thanks!
