I've got a pistol grip in my '70 Swinger. It came with the car, but I'm sure it's out of another Mopar. B body? E body? I don't know. But I like it. Way better feeling than the T handle I had in a car years ago.
Thanks everyone. Yes, I have succumbed to the disease Sublime mentioned. Now that it's warmed up outside, I can get the headlights working, put the chrome valve covers on, and so on...
