Well, been there with my '73.........by the time you find the right parts, you may as well have already bought a floor shift column and installed it. It wasn't that bad switching columns, really. Maybe someone else can suggest a way to swap the collar, but I don't even think they are interchange-able. I could be wrong, but side to side mine didn't look the same. What car are you working on? Maybe yours is different than a Roadrunner, and someone else here can help. Good luck!
