missing teeny tiny part...

Morning all,

        it would appear as I approach the final assembly of the Bugeye that i 
am missing one bit (Ok, I'm missing lots of bits I just don't know it 
yet ) and I am hoping that someone can help.  Does anyone have for 
sale/trade the barrel that the actuates the heater vent.  This is the 
barrel that the heater control cable hooks into and the barrel fits 
into the heater control valve between the fan and heater core.  Thanks 
for taking the time to look!

Lester
