Decals can go on windows and fenders, and are safe for use on valve covers. When applied there is no background and the silver will be a mirror finish. I only have one of each, so it will be first come first serve. If enough people are interested, I will start an auction on eBay and charge $2.50 per decal with a $2.00 shipping charge.
This is what the decals will look like when applied. The "307" is actually red, but came out orange in the picture because of the sun.
