Heater box interchange

[cdstl]

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

between model years 72 and 73 the holes in the firewall for the heater core lines, ac lines and blower motor moved or changed size.
it will fit directly in a 73-76 A body.
with modifications to the firewall it can fit in a 67-72.
