Power windows

I was collecting a set for my 69 Satellite. I am unsure if these are correct. Do I have two different years here or is it one set. Thanks. 

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

Thank you for your help.

Are those from a b body or a C body. The base and the gears is the same but the window arms are longer. I install a set from a C body on my 68 GTX, you just swap the arms. I also drilled them to take out a 1 1/2 lbs from each to only add 10 lbs from adding power windows.

I admire the effort, not sure I would have been that aggressive on that long arm, lots of torque.
