The whole seat/number plate support system, which will also provide support and location for LED tail/brake lights and plate behind the number plates, was a source of question until this whole "horseshoe" idea came up using the stock seat mount location. It''s not exactly what I wanted because the seat doesn''t angle up at the back. I should have done a better development for the fabricator, who did the breaking of the part. I did do some reforming because it was actually square at the corners where it now has a 45 angle... one of those ideas that took inspiration of sitting in a chair and sipping a beer to get the courage to take the chance of screwing it up. It actually came out fairly clean.
