NiceOld(s)Car

I am restoring a 67 442 that had factory air and did not have the rally guage pac. I was fortunate enough to find a local dash with rally pac tach and guages in it and the seller had the wiring harness out of his car, however his car didn't have AC. Will my wiring harness or his be the better fit or will I have to mix and match?

Thanks for any information you can provide.
