actually theres a company that does the mirrors for gm that likes to do the threats. real class act of a american company. but you know what if you do this yourself or have a friend do it for you, theres not a d@#$ thing they can do to you. just dont advertise you will do it for a profit cause thats when the totem pole pricks will stick you. kinda sad considering they, murdoff does not have a clue on how to put turn signals into motorcycle mirrors.
