    What body style is what. So many parts catalouges refer to body style and I would like to know exactly which style I have. It is a 2000 Yukon. I have been told it is the same as the Tahoe but the 2000 chevys look different. Does anyone have pictures of the different body styles and to what they are refered to as? Thanks for any help.

    Very useful information. Does the classifications by years also hold true for trucks?

    Thanks to 99'HEARTBEAT for the research and time for the posts! Cleared up a lot of my confusion.
    Maybe should consider making this a sticky.
