I recently rebuilt the headlight motors in my firebird(thank you top down solutions) and they work great. My problem is the driver side headlight closes about 1/16th of an inch to low. It is below the nose clip, by 1/16". I cant find a lower limit either. The rear can be adjusted by loosening the bolts and adjusting it, but the front I cant figure out. I tried to screw it out with the manual screw, but it sinks in anyway. I guess the motor doesn't stop till it hits the lower limit. Any way, other than shimming the lower bolts up, to fix this?
