Most vintage air units do not use mechanical cables. And I just found out that the car is a 66 not a 64, not that it matters to the ac installation only in that the wiper arms are close under the dash.
For engine compressor bracket kit for a early mopar, you will have to do some work, but it can be done. Mount the ac compressor as far rearward as possible to use a mechanical fan setup.
