AC Compressor hoses connector bolt

[70inline6]

I'm reconstructing the missing AC system for the 83. I got my parts on order but one thing I'm missing is the bolt that connects the dryer and evap lines to the back of the compressor.

Being as there aren't any square body trucks in the parts yards here locally, anyone replaced/disconnected/re-connected these lines recently that can tell me if it's a special bolt or one I can pick up at Home Depot?

Thank you
