Hi Dave ,I would like a complete set too, I have a 71 challenger convert. I would like them without the holes in it because I'm converting to power windows. My originals are mint!
On the rear panels of a Challenger, I am quite sure, the opening for power/manual is the same location. If you look on the back of the panel, you will see a rectangular spot where it would have been punched for PW. With manual panels, you would need to cut out the area for the switch. The front is a different story, and for a pristine job, new panels are in order. I did see a car that had a round plug installed in the manual panel and it was not that obvious. I think the guy used a donor panel and used a hole saw without the pilot bit to make the plug.
Not sure about Cuda/Barracuda, they may be two different panels.
