The first two were just anodized black like others have had done. On the first set I had chamfered the screw holes too deep and had the plates milled, so the screws were a little recessed and the edges of the plates stuck out just a teeny bit too much. The second set used their stock sheet metal and fit the chassis much better.
The third set was a complete replacement of the chassis and plates using natural aluminum.
Here are some photos:
