Heater box interchange

I pulled a non-A/C heater box out of a ‘75 Dart because it was clean and easy to pull.
The question is what other A bodies will it fit.

I posted on Moparts and got the reply that it may only fit '73-'76 A bodies but I just want to ask the same question from you guys.

‘67-‘69?
‘70-‘75?

All of them or none of them.

Thanks
