Defroster Vents

If I recall, there was another year van that the top was the same, but the hose fitting was square instead of round as well.

Those are the ones I was thinking of.

Just called my local dealer, and the vents for a 79 B series van are part number L716DX9, black only, still available for $34.30 list. I do not know if these have the correct hose connection.
