I had one years ago and yes you have to cut a big hole for them to fit. Even 30 yeares ago, one designed for a mopar was hard to come by. I got one for a muncie and made my own linkage rods up. You have to lift the handle to reset into 1st gear, so you always have to remember where you are as you have to shift and let the vertigal gate fall to get 3rd and 4th gears. But man you can bang some gears with it. People used to think I had an automatic in the car.
