I added them to mine. I used NOS original 78+ motors and rods but rewired to suit more modern central locking kit and leave off the door switches. The car can now be unlocked via key fob. My 78 also has a 77 style door shell, so the dimples for the brackets are different. I nearly started drilling without checking.
Here's a link to just the door install. Obviously, the forum guys found it worthwhile of my time to upload! *crickets*
