If you want to go back OEM style, classic auto air sells the complete clamshell assembly with all the vacuum motors, switches evaporator and heater cores and damper arms.....basically all the internals and externals.  I got one for my 72 and it worked out great.  However, the blower motor is not available.  Used ones are on eBay from time to time but are rare.  If you still have your original motor......DONT GET RID OF IT!    The motors that are advertised as being for A/C are in reality heater only motors.  They dont have the RPMs to push air thru the 3 vents.  You can also buy a new modern setup from classic auto air with electrically operated dampers etc.  No messin with vacuum hoses and motors.  Those are expensive but you're guaranteed to get the correct motor for good air flow.
