We had the same need for our LSA fender badges. The billet badge option is nice but we wanted a badge that had the same contours front to back and top to bottom as the original oem stock badges did. We ended up designing our own on the computer and then 3D printing them.
Not a cheap option but it was exactly what we wanted. We also designed in a relief in the back of the letters to effectively hide the double stick tape we used to attach them.
Finally, we also printed a matching template to position the letters in exact location when installing them which made perfect alignment a no-brainer.
Here is a pic of the first badges we made this way. They are the same thickness the oem badges were. We are now printing new ones that are a little thinner so they will better match the thickness of the side marker light bezels next to them .
