I'm looking for help in getting my 84 GSL-SE registered as a collector vehicle. NJ Motor Vehicle has sent me a letter saying i need to "submit evidence from either the manufacturer, a recognized car club (on letterhead) or collector organization that" my vehicle "was issued in a limited edition quantity or that a limited quantity of the original production run remains."

I'm assuming I can contact Mazda & get something from them, but I was hoping someone can point me in the direction of a local club or org. I'm new to the area & don't know what is around. Thanks
