Can anybody identify this

[Nevada dan]

All I was told by who I got it from was it was out of a B body
Can someone identify what years it was

A/C heater box. 1966-1970 b-body, there may be some differences year to year I’m not aware of.

The AC box is different than just a heater box.

This is a 65- 67 b body prior to going to fiberglass case in 68 to 1970

They were metal 66-70 for AC which is what is pictured.

yes the heater only was fiberglass 66-70

control valve lower right end of the case is 1968-70 cars only. 1967 and older do not have said valve
I know C body air boxes of same years are very similar if not the same but have no idea the differences,,,if any
