Replacement bolts?

I was working on my '83 Chevy Celebrity, hooking up the shift cable, and I lost one of the bolts securing it to the transmission casing. Can't seem to find replacement bolts anywhere I look, could I use any 13mm bolt? Is there an official replacement vendor?

Take another one off and take it to your local hardware store, they'll hook you up. Match the hardness and everything.

How do I check for hardness? This is my first car, and my first experience actually working on one.

I meant they'll do all that shit for you, its stamped on the bolts though if you wanna read it yourself.

more specifically, he's talking about the "grade" of the bolt, which encompasses hardness, grain size, and a few other factors which are defined in ASTM or whatever your local governing body is. Just get apples to apples or higher.

Thanks for the help. I'll go looking on my next day off.
Chevy thread?

I really miss that type body style, that's how cars should look in my mind. Fuck all this new roundness.

It's got a very American look to it. Why have cars become near identical to one another?

My buddy has one that is absolutely mint. A weird choice for a summer car, but his other car is a Citation...

Diesel or gasoline?
