Early A heater controls ????'s

I would try it and see, after all, the cable are low meaning the cable are probably longer or the same, if 63 is slightly longer, I would think they will work. I might be able to get the parts for you if they are different, not sure if the controls are the same or not, I know there was also a nice aluminum dash trim bezel on the 64 model too, might be able to get the 3 piece trim set too if you like :glasses7:

Let me know what you find out, I have shipped parts to you before and will do it again if needed :thumleft:
