318 custom badging?

OK, here is a way to do it for a pair.

Get a pair of 1.5" x 3" x 1/4 aluminum plate. Then with a computer controlled end mill you machine out the desired emblem shape and insert letting.

Then use black paint for the background and then polish up the remaining aluminum like chrome.

Then stick them on with double faced attachment tape.

Water jet could be used to cut the shapes out of the 1" aluminum plate too.
