HELP!!!! Is this AC box correct for my 72 scamp?

HI all,

Is the AC box shown below correct for my 72 scamp? Will it even work for my car? I am told this box is for a 73 or possibly a 74. Is there a slight difference between this and a 72 box or would they be the same?

If this wont work can someone please post a pic of the correct AC box? I will also post in the parts wanted section.

thanks in advance
