E body, where can I get screw for turn signal lever

Putting the steering column back together on the wife's Challenger and I noticed the long screw that holds the turn signal lever in is a little boogered up.

Anyone know where I can get one or what size it is?

Thanks.

You might take it with you to Ace hardware, they have the most extensive of nuts/bolts/screws by far of any store I've ever run into

I've found some specialized fasteners at fastenall. Their online catalog is pretty easy to navigate.

I have an extra you're welcome to.

Thanks for the offer.

I'm going to take it to my local industrial fastener supply house and see if they can identify and match it.

If I don't have any luck I'll be in touch.

Ace is the place, even though they are only open 9 to 6 in Graham.
