WA Cruise Control-OEM-Very Complete, but what year???

[PICKMUP]

[B]This cruise control was requested by Pete DeadheadNM, so he does have first call on it.
It appears to be very complete, w/all connections and hardware intact. I did not remove it so I can't guarantee the year. It came with the factory tilt column, so it should be 71 or 72. I think some of the guys on here will know for sure and chime in.
The system in the other page/thread from 2009 was $425 and I think this one is more complete........................so, I will sell for $500 shipped & insured. Here's the pics.
