defrost duct

My 67 Belvedere has a broken defrost duct on the passenger side. I haven't been able to locate a replacement. Any help? Thanks!

Scarce as hens teeth. I'm going to test one with some epoxy.....

If you don't need totally correct, try NAPA p/n 813-1509 - $1.99 per foot in the Detroit area.

Cranky - I fixed mine with epoxy once, but it didn't hold. Maybe I'll try a different product.

Dart - I actually need the molded plastic piece that the flexible hose attaches to.

Thanks for the replies, guys!
