73 Duster Blower Switch and Heater outer box w/ac needed

Are you speaking of the low/med/high fan switch? I have a NOS one.

What outer box are you speaking of?

I pulled my 73 Duster box with a/c out and took it apart to put in a new heater core. I am not going to put it back in. If you want pics, please pm me your email

I also have a complete box that I do not intend to use.
