There was a guy on ebay selling repro's. They are pretty good, the red back ground is a little lighter in color and the numbers have more white on them.I compared them to the n.o.s ones I have.(not for sale)here are some pics of the decals
the top decal is the original bottom one is the reproduction copy . He has them in the 10hp also-I think he was getting 15 bucks for them
