Thanks BC59. On mine there is a metal pipe coming thru the floor behind the drivers seat in the location you mentioned. When the truck is running, I can put my finger over the pipe and feel the suction.

I'm not looking for O.E., just something that will work. How much would you be asking for your set-up?

Thanks again.
