Anyone Know This Ignition Coil Support Bracket Part Number?

I'm pretty sure they were installed on the early A Bodies. I saved 2 of them from I think 65 Valiants or 65 Barracudas. My older brother got 2 Barracuda parts cars and both had them. I've never seen them on the 67 up cars. And I'm thinking it could be for AC cars to move the coil forward to get more clearence for the AC lines that connect to the fittings on the firewall.
