Evap core delete pipe?

hey guys I removed the a/c on the car a few years ago and I am pulling the dash soon, does anyone have a pic or some info on the pipe that was fitted to heat only models? Im thinking its just a connecting pipe that goes from the blower box to the heater box.
Thanks

I'd say you'd just have to fashion something out of thin sheet metal to act as a bridge, or try to find a way to gut the original housing and reuse it.

you used to be able to buy the plastic duct that went from the blower motor box to the heater box, but since its NLA (i think i bought the last one?) the best bet might just be to gut the evaporator box.

making a duct wouldn't be too bad, but the shapes of the openings on the blower box and heater box aren't the same, and they are odd shapes
