Back to your original question, FYI all of the USDM Galant VR4s are the same car with the exact same options except for color, sunroof or not, and stereo choice. The only other differences you are going to see are in the '91-'92 differences such as a different ABS unit, grill, tail lights, wheels, badging. So power locks were not an option but standard along with everything else.
