Ok, I got the vents and fresh air box installed back in my 72SB. I realize
now there should be some tube that spans from the box to the vents - who
carries them?

Second on my list. I have new heater boxes and hoses (boxes installed by
prior owner, hoses by me) and I get GREAT heat to the floorboards. Now, I
see the lever that shows HEAT-DEFROST. I pulled it up for defrost, but no
heat comes out of the window vents...not sure why. What am I missing? I
have the fresh air knobs hooked up, flaps are properly opening/closing.

Thanks for any info...winter is a comin'...
