Hi,

I need help with my a/c in my 71 240z. When i bought the car the box under the dash for the a/c was gone the rest of the system is there. I would like to know if a box out of a 73 240 is the same as the 71.

looking for a z ( have found one)

I believe most of the A/C units were put in by the dealer by some aftermarket company. None came with it from the factory. I guess you would only need to find one that will fit under your dash.
