I got a pair of '07 Ultra Classic air shocks off ebay ($46 shipping & all!) and about $40 for the air line stuff , for my 1981 FLT . What a sweet diffrence!! Well spent money for such an easy mod to do ( the shocks just bolt on , and was an existing screw to use for the schrader valve ) And what a nice cushy ride!!! I strongly reccomend this to others.
