Does anyone know what size ducting goes inside on the passenger side from the vent to heater duct?

All the venders seem to be sold out.

This one? Looks like 3".

The one in the red circle.

This is for my 85.

This is a 1983 Dash Pad, I have a 1985 and can measure it if needed ... This looks like 3" or 3 1/16"

There may be one at the salvage yard I have been going to off a 1987 Suburban ... not sure, but I can check if you need me to.

I sure would appreciate that sir. Most vendors are on backorder or crazy on price for what it is and the last one I bought, didn't fit (too small).

I just put mine back together and bought new 2 1/2 from vintage Air, way to small. It is just a tad over 3". I took the original hose out, cleaned it up and trimmed it and put back together, seems like it is going to work just fine.
