A/c Compressor Bracket Lower Mounting Bolt

[EOLIVER]

Just recently replaced my waterpump on my 1987 coupe and realized that I have misplaced the lower mounting bolt on the A/C compressor bracket. Does anyone know where I can purchase a replacment bolt?

I thought about ARP, but would need to know the size specifications for this particular bolt. Anyone have any spec information, photos, or can suggest as alternate fastner?

The local chevy dlr should have one.
