A/C Duct

I know its been discussed before and nobody is making them currently but does anybody know anything that will work? The center duct and driverside duct is not salvagable at all on the 78 Bronco I just bought. It would be great to have the heat and a/c blow out the vents instead of just everywhere behind the dash and lower vent.
I took the current ducts out because they looked about like a slinky all the material is gone from them its just metal. Everything in the junkyard looks the same.

I've got the same problem, A fix i discovered via a thread on here, is this:

Take the remaining coil and clean it up as best you can.

Buy some vinyl fabric and cut it to length of the coil.

Spray with headliner adhesive

Wrap the coil in the fabric, let it cure.

reinstall.

You can also buy a section of vinyl vent hose 4inches wide for the drivers side vent. You can get it from your local hardware store. The middle vent you will have to do the above described way to fix it!

Can you get some out of a newer 2000+ JY Ford truck and adapt to your older vent ends? I have heard of that being done.

I seen those on ebay last night. I wonder why some ducts are solid plastic with a elbow on it? They should all be like that. On mine from the lower vent all the way to driver vent its that material that deteriorates with age.

Some 78/79 Bronco's have the solid plastic piece going to the drvs vent.

The top flex piece came from a 73 F100 and the bottom plastic piece came out of a 78 Bronco.

Sorry parts already sold.

I hit the jack pot on vents the other day. I got 3 driver side vents and 3 middle vents. One of the driver side vents was solid plastic, that's the one I used. Its great having all the vents work.

Nostalgic air makes them. They take round hose into the back but I'm sure they can be modified.

Does anyone have the dimensions of the infamous rectangular center / middle A/C duct ? I am scheming up a good and cheap solution for all.
