A new found friend (on this forum - He's in Texas, I'm in California) is looking at the TT rear ends he has to see if any are marked like mine. Since I now have a photo of it I thought I'd post it and see if any of you have ever seen anything similar.
To the best of my knowledge my TT is an '18. This photo shows the right side pretty clearly, but the dust covered left is the same under the dust. Anyone have any clues as to what these numbers may signify?
