47 WC defroster

[dgrinnan]

It appears my 47 1/2 ton has never had a heater/defroster.  I have a nice 40's heater to install.  What have you guys done about duct work from a heater to your defrost outlet?  I will get under the dash to confirm but last time I checked I don't think there is anything there.  do I need to source and original set up from a donor truck or have anyone fabricate their own?  What did you use?

There are pieces that attach behind the dash and transition to round duct hose that you can then connect to a heater.

I will take a closer look.

I checked.  There are no connectors or duct work under my dash.  I can look straight up and out the defroster slot in the dash.  I see the two brackets the connectors should attach to but they are gone.  I think the flex pipe is suppose to be 2"?  I need to figure out how I am going to attach and vent out the defroster openings.

They were optional so if you never had a heater setup your truck probably never had them. I wonder if DCM or Roberts has reproductions? A quick Google shows Chevy trucks have similar looking pieces for about $20 new

I have been searching google and I have left a message with DCM Classics.  They don't list one.  They might have some in their yard.  Waiting to hear back.  I am also reteaching and exploring my options to fabricate them if it comes to it.

Not sure if the ones I have are Mopar or aftermarket, but they screw right in to the underside of the windshield defroster vents in my dash on the 39. I'm relatively certain it should be the same for all cabs up to 47?

That looks right.  I agree, 39-47 should be the same.  Now I just need to find a couple.
