classic auto a/c for a 73 duster will a 72 system fit?

[panheadchuck]

i been looking around for ac for my 73 duster 340, classic only makes an exact fit kit up to 72 . it says it may work for 73 . The install thread on the 72 demon on this forum looks pretty close to 73 duster controls and box. i just dont want to buy the kit and find out nothing fits , Are 72 and 73 dusters pretty close as far as the hvac sytem

The heater control panel on a 73 is a bit different than a 72. My fan switch is horizontal & a 73 is vertical. Also, your radiator may be a 26" versus a 22" on my 72. I'm not sure where your openings in the radiator support are?

Most of the rest of the kit should fit just fine...

Here's a pic of the heater control panel.
