I just got this in today, it was from a 71 Chevelle convertible, same as your coupe. I did not test anything since it was all in a box already, comes with what was the rear harness and a section of what might be passenger door. Has those original door jamb tubes not in photo but included. Price is $400.00 and shipping Fed Ex will be $40.00, Paypal accepted as sales. I also have a 4 speed tilt column for $375.00, shown in last photo. Joe 602-298-7090

 

I'm interested in the column. Do you have the turn signal and tilt levers?

 

The levers are for a Chevelle which this came out of. Thanks,Joe

 

Sold Power window parts, column is available.
