I'm installing vintage air in my non a/c '69. I ordered new a/c model dash so it would have vents in center, not hanging under dash. I ordered the louvers, but there is nothing to attach them to. Does anybody know where I could get the piece that goes behind lovers that ducting would attach to?

Which louvers did you order? Factory or Vintage Air?

Typically for factory A/C parts, especially ducts and such, Ebay is your main source. That is where I got one some time back.

The vintage air center vents snap in.
