What year was Power Windows and Locks offered?
 

Looking to install in a 73.

The first years for power windows and locks was 1977. With that in mind you should be able to pull the whole setup from a 77 up truck including wiring and all the internals of the doors and install them on your 73. Of course the complete door off a 77 truck would be a good swap also for the setup without as much disassembly and reassembly.

Tried to post this last night, but my account is all screwed up right now. So I registered again.......

It was 77, 77-91 doors are the same. You will need to change the complete door. 73-76 doors can't be used for the power motors. Here is a pic of the comparison. I can tell you what the problems will be if you can tell from the photos.

There are also 2 versions of the power motors. The early style 77-80 are a little stronger/bigger motor than the latter.
