I'm finishing up some interior stuff on my 4+ year restoration project. I installed the heater assembly and went to hook up new heater hose to the defroster ducts. My heater has 2 outlets: the passenger side exhaust duct measures 1 3/4" OD and the drivers side exhaust duct measures 2". The hose I purchased will fit the 1 3/4" side fine but not the 2". I seem to remember that the hoses are secured by a rubber collar and no clamps. If this is the case I'm missing a collar for the 2". Does anyone have a pic of this set up and where can I find a collar? Or am I stuck with fabricating one? I took 400+ pics of the truck during disassembly but don't have one of the heater/duct hoses. Thanks.

It never costs more to ask and it never costs more to think big.
