Need an Air Brake Caging bolt near durham/chapel hill

[yodaman88]

I know it's a long shot, but I'm in chapel hill right now with a right rear air brake that's sticking on a school bus I need to drive back to wilmington. Does anybody know of a store or truck repair shop from burlington to raleigh that's open and would have a cage bolt or maybe one of you has a spare I could buy or borrow and mail back. Crawled under the bus to discover that both cans were missing the cage bolts.

edit: got it covered out at the TA truckstop in mebane.
