These are impossible to find. I found some at a swap meet. They appear to be very nice reproductions.
Note: Air cleaner is NOT included.
2nd Note: This sale is for the decal ONLY. The chrome round air cleaner is only pictured so you can see what the decal looks like installed. Do not message us after purchases telling us you thought you were getting the cover. Again, sale is for DECAL ONLY. This decal is a vinyl sticker, it is not a metal insert.
