hello I´ve just purchased an 89 flst heritage. This is my first Harley can anyone tell me the factory differences between the flst and the flstc. My bike doesn´t have spot lights did the flst come with them or only the flstclassic. Vin#1hd1bj I was told that 1hd1bf would be a fat boy. just trying to find origin of this bike any help would be appreciated thanks
