Can they send you some pics of it.  If it looks exactly like the pics below then it should be no problem.
Are you still looking for bumper brackets?

Yes, there are 2 styles of controls that I know of & see no reason not to
interchange them on the same car.  Thanks for confirming the interchangabilty!!!

everything on AC or Heater are interchangeable as far you have the complete setup for the right car. I mean...

Heater box ( or A/C ) to a heater firewall... the main diff is as far I know the blower cooling line access and of course the in/out lines.

Wiring and controls are the same ( same as above, between Heater and A/C setups themself ) EXCEPT for the lever fan switch plug... if you find the right plug to the right control you can easilly interchange using your actual wiring.

72 heater/ac box also uses screws to hold unit together - 73/74 heater/ac boxes use screws on the sides and clips top and bottm.
