I ordered some reproduction decals off Ebay. The kit comes with all 3 stickers including the warning label to parents on the handle bars. The size and style is perfect, but the font is slightly off from the originals. You can only tell when comparing them side to side anyway.
In about 2 hours everything was put back together. I would still like to find some nos (new old stock) grips as the yellowing would not come out of the original ones. As of 2012, someone is selling some re-pros on Ebay.
