Stroppe had adapters made for the automatic transmission and the transfer case. The first two pics are from my 1971 Stroppe. In 1973 Ford had produced the Bronco with automatics themselves. Looks somewhat similar, without the STROPPE in the casting. The third pic is from my 73 Stroppe.
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.
