in identifying this "option"? My 74 tii parts car has an electric sunroof. This is definitely an aftermarket item. It will extend up a few inches in the back or slide back fully open electrically. It also has a manual open shut door that slides forward and aft. The assembley almost takes up the entire lower surface of the roof, and is riveted to the body on each side. The assembly has drains in each corner which feed down the pillars just like a factory installation. The motor, which is identified as "Rockwell" is in the front of the assembly. Has anyone seen one of these and where can I get parts for it? It appears to be complete except for some way to control it, ie. switch or control handle. I have yet to put 12V to see if it works, maybe next weekend.
