Pontiac Firebird 1967-2002 - Battery Terminal Bolt?

Just picked up a new Trans Am. It's missing the bolt for the positive battery terminal on the wire. Is this something I have to get from GM, or should a local Pep Boys, Auto Zone, etc., carry it? Thanks...

I know you can get them at any auto parts store. If you find the correct size you can even go to home depot or lowes. If you have 2 cars like it sounds then you can take off the battery off one and just bring it to homedepot.

Thanks! I was going to grab the negative cable bolt to take to the hardware store as that's still in place on the 01. Just missing the positive bolt.
