AC/Heater box rebuild

[j_anderson]

Restoring my '72 Swinger and I am rebuilding my AC and heater boxes. This picture is not my box but I have this same opening at the floor vent. I dont remember ever taking this vent duct work off years ago when I disassembled my car so, I'm sure my car was missing this piece. Can anyone tell me where I can find one?

Also, there are spring metal washer/keepers on the blend door actuator rods. I have broken 2 of them during disassembly. Can anyone give me a link to some suitable replacements?

Post an wanted ad on here for the vent, someone will likely have one.
Oreilly’s has those clips on the universal part racks in the store.

Detroit Muscle sells nice rebuild kits for the heater / ac boxes.
