Confused on Heater Control Valve for 1975 Duster 360

When I got it, my 1974 Duster 360 was 99% original. It came with a valve that bolted to the fender.

It Looked like this. (The pic comes up when your part number 3503487) is searched.)

When it stopped working in the 2000s, I replaced it with the Amazon version you show. seen here hanging from a hose.
