Can someone please tell me where I can get the rectangular cloth air duct hose used on (at least) 68-69 GM cars from the dash vents to center ducts?

I'm almost positive I saw on an Olds parts house that had it last week when looking for something else, but now I can't find it. The Parts Place has round hose, but would really like the rectangular if possible.

 

try an A/C (or better yet Marine A/C) supplier (cruiseair, marinco)

 

You might want to get in touch with "Olds 64" (link attached). I seem to remember that he found or knows where to get this stuff new. If anyone remembers the thread about this, maybe post it for 68 Tom.
