87 Avanti door lock actuator's Part is from a '87 Monte Carlo. Chevrolet & AC Delco # 22062740. No bracket. $54.00 - $95.00 Standard Motor Products # DLA1. With bracket and rubber body boot. $76.00 - $157.00 Dorman # 746-014. No bracket comes with rubber body boot. $39.00 - $68.00. Standard and Dorman come with a nice rubber boot around the body of the actuator, this is not part of the orginal but would be good for keeping out the weather. The bracket is held on with 4 screws so changing it over is easy. I purchased the Dorman actuator for about $39.00. Jim Wood - Sep 2010
