De-Frost Ducts

71duster

I am only going from memory (cause it has been a long time since I worked on a heater box), but I think there are some metal clips that slid over the lip of both the heater box outlet and the defroster part in the dash. The had some sort of tooth or seration that would hold the hose on.

I had the same problem with the original hoses until I discovered this clip was missing. I don't know if they would work with the aftermarket hose.

PS It was nice to finally meet you face to face at the race track. Too bad I was having an bad night and its too bad I have to drive a &*^*y race car, but I couldn't pass the opportunity to drive a race car for a season without actually owning it! Also this winter I am planning on painting my 74 duster and getting it ready for a summer of driving it next year, so I'll be back in the duster world again!
