I accidentally clipped one of my side mirrors when pulling into a garage today and need to get another. I was looking online and the mirrors are different for 94-95 and 96-98 mustangs. can someone tell me the difference between the two? if its just the wiring is diff for the power mirror, then i can deal without a power mirror. or is it the actual mounting points are different on the two? any help would be great before i go search through the junkyards.
thanks,
ryan
