I have those parts from a 74 Challenger. The window crank shaft and bracket on the regulator is shorter on a Cuda than a Challenger, they can be switched by drilling out the rivets. I do have a Cuda regulator
I am in need of the passenger side inside window "cat whisker" that attaches to the inside plastic door panel. I only need the one I don't want to spend $200 on a complete set.
Don't laugh, I would try GOOP adhesive. I usually keep a tube or two handy, works on anything and remains flexible. I used it to hold my 2005 Crossfire roadster window to the convertible top ( common problem with the roadster), after 3m failed.
