Looks like a set of 4 to me. Don't know what year the system fits, but if your 69 had power windows, there is a pretty good chance that is what it fits. The one with the 4 button switch is the driver's door. My guess is the one to its right is the other front door. The bottom two should be the rear door units, The one on the lower left is laying the wrong direction compared to the others, and may not be all the way up (or down) like the others are. Gene
