I got the idea when I saw the promotional 2 piece extruded aluminum 50th anniversary Mustang (have a few of them).
In my free time (at work) I made a CAD drawing of the outline of the 03/04 Cobra coupe along with the Mustang inside and SVT inside that. Once I found some free wire EDM time I was able to cut it finally. Here's the outcome. I might end up polishing it to remove the tiny entry and exit tabs.
