70 a body heater box 73 duster

[bradford]

Hey guys and girls. I have a question about my 73 Plymouth duster. I have a 1970 Duster heater box that came out of one of my parts cars. Will this 1970 duster heater box bolt up in a 1973 duster or do I have to get a 73 heater box. Thanks in advance.

Totally different firewall bolt patterns, outlet locations and the connections for the controllers are different.


Save time and work and get a 73 to 6 unit and bolt it in and then have a six or twelve pack in the time you saved lol

Totally different firewall bolt patterns,

Are you sure?
Cuz I think I have a non-A/C 73 Dart box in my non-A/C 68 Barracuda. I think but not quite sure........ If someone would have asked me this yesterday... I wouldda said yes.
Now; I don't know.......

Absolutely, I have 67 to 72 and 73 to 76 cars and they are different.

Not saying it can't be made to fit with modifications but definitely not bolt in

Green one is a 69 dart and the black is a 75 dart

Late 74 and up had the vent tube but it's the same bolt pattern and footprint as 73 and early 74

All 67 to 72 i have ever seen are the same except the early ones had a metal squirrel cage and most 71 and 72 had a plastic squirrel cage.
