Very hard to find by now. What type of shifter do you have Floor or column? You might be able to find a column shift. My 77 parts Aspen had one of those. As for a floor shift column, that is a unicorn for an F mopar.
If anyone is looking for a tilt column, column shift with factory cruise, there is one in Tulsa Oklahoma on this black 77 Volare wagon. The owner was very friendly and reasonable in price. I scored the entire interior and the Road Wheels, along with a bunch of other stuff. I didn't take the tilt or cruise. If interested, I can put you in touch with the owner.
