I just bought an "all original" 550LTD "other then internal engine modifications", it is f-ing hot, Wow; I love it. Here´s whats cool!!! 1981, 19,000 miles on it and its to spec front to back, top to bottom! It is almost perfect 99%! Most important I paid $600.00 for it, it needs nothing at all! (one owner since 1981). Let me know if you want to chat?
