Don't know if that's what it's called, but that's what I'm calling it. I know we have a classifieds section, but I couldn't find one by searching. Hopefully it is ok to post here. I need one for a 1954 with a recirculating heater. If you have one please let me know through PM. Thanks.

 

Finding someone that would part out the heater box and duct might be slim but heres everything on E Bay.

I bumped this up to the top again because clintonvillon has a link to a heater reducer he has for sale.
