Is your car a vinyl headliner car? If the cardboard headliner proves to be too much of a chllenge you can still mount the console in your car with a little work.
I was able to install a factory overhead console in my 72 Cuda with the standard vinyl headliner. Is fully functional, and looks like it came that way. The only additional part I needed was another dome light support from a donor car. I located it forward of the existing support and it provides the forward attach point for my console.
To be fully functional there are some odd and ends that you will need to chase down. Some of which are the low fuel relay, wiring, secondary door switches, overhead console dome light, etc.
