yeah alot of parts guys have a severe case of laziness, anytime you say a year before 1993 its nla with out them even looking, our local dealer has a good parts guy, u can always call any parts guy all around the country. i've done that before i was trying to get the unlock code for my gfs 90 cabriolet radio some dealers just wont do it and some want to charge, i just kept calling around till i got someone to do it.
