'69 Dart "where does it go" question...

Hey guys:
I am reassembling the dash on my Dart after I restored it and I'm having a memory lapse. I know WHAT this thing is...it's the support for the driver-side defroster hose, but I can't recall where it attaches to whatever it attaches to. All I remember is it was somewhere to the left of the radio when I pulled the cluster out.

There is a slot for the fastener and a tab to locate the bracket. The witness marks for the bolt head or nut at the slot are visible on the side OPPOSITE from the tab.

Thanks in advance for any help.
