73 duster ac box into 72 dart

I put a 71 dart factory air in my non ac 68 cuda. The boxes are the same both years for my swap. It was a lot of work, but turned out nice. The 67-72 have the push button controls, I think the 73 up have the two lever controls. I don’t know anything about 73 up, but I had to do a fair amount of firewall work for the swap. Don’t know if 73 is a direct interchange.

For $50 may be worth a try. You will need the controls, lines, compressor & evaporator & get all the pulleys too. Probably should rebuild box with kit from Detroit Muscle. I probably worked on mine for 80 or 100 hours. Spent about $500-600.

The aftermarket market would have been a lot easier, but about $1500 to $2k.

Can help if needed. Think I still have a firewall template I made
