what are the differences between a 55 second generation, a 56 and 57 truck, all things being equal, like all are 3100 series ?
is there a difference with tail lights, blinker lights, etc ?
i want to be able to tell them apart from each other. if you have pics, please post. every time a friend asks what year truck it is, i say 55-56-57. LOL.
same with 50-54. kind of look the same to me, although i am a beginner here...thanks in advance....
