Confused on Heater Control Valve for 1975 Duster 360
I'm in the process of swapping a Eddy RPM Air-Gap onto my wife's Duster (Factory 360 car with A/C and Cruise)
I spent a few hours searching online for proper heater hose routing last night which I finally figured out (I also have both 1975 Factory Service Manuals but they're a little generic and don't have specifics for a Duster 360).
I ended up ordering this one as a backup:

and one of these:
1975-1976 Chrysler Plymouth ,dodge heater control valve 3846381 | eBay
The one that was on the car is the one I attached a picture of which appears like the one shown in some images of 72-74 cars here.
If I could at least figure out which part number is correct, I'd buy a new/nos one, but I can't seem to identify which one it's supposed to have.
