Hi Everyone, my son has a 2003 Grand Prix GT. The drivers window no longer goes all the way up. So we decided to replace the door window motor. My problem is that no parts house can find one like what is in his car. The one they keep trying to sale us has a smaller hole patter than the one in is door. Can someone help with a aftermarket part number? The number on his motor is F8-578VA Is that the original manufacturers number?
