Can you put an overhead console in a car that never had one and has a regular headliner already installed? Do you have to add anything to hold it up near the windshield?
The Cuda 70-74 can use/receive a GC headliner board with very few mods, the 70-1 Challenger uses the rear window plug inner trim to assist in retaining and finishing the rear section of the headliner, the sunvisors, rear view mirror, and shoulder seat belt, and clips, along with the headliner perimeter U clips and the overhead Y shaped embossed bracket in discussion help retain the board in the car, the bows from a cloth headliner vehicle are discarded, as far as fitting an overhead console to a cloth equipped car, anything is possible, but that would involve some custom work on your end as the overhead console only has 5 mounting studs that normally retain it to the board, so you'd have to fashion some form of a support plate that would sandwich the bows in the headliner to hold/support the console to the cloth headliner
