I had them installed in my (2) Two doors, nothing needed cut. Although one jackass did drill holes in my fender of the Stroppe to mount the switch because he was too stupid to read the instructions and see that there was a place for it on the mount.
I would like to add that I dislike the lack of drip rails like the Wrangler has so you can have your window down without water pouring on you when you turn first thing in the morning, from the dew the night before.
