A/C B-Body heater box FRESH AIR DUCT

Does anyone reproduce the large flexible duct that goes from the heater-a/c box under dash to the cowl? This the the one about 7 inches in diameter and has metal ends. Anyone have a decent used one to sell? Thanks

used only,
good luck finding a nice one,,your gonna need it

Have you got a picture of one?

Is it round on one end, square on the other?

I have a few pieces of mid/late 60's B ducting.

One just sold on Ebay a while back.

Yep. I've had several of these over the years and never had any problem selling them.
