I made a custom laser cut overlay for a customers rig about 6 years ago. I still have the CAD file and could lay one out with the holes for any stock items or swtiches (or other stuff) and have it cut for in a week or two from aluminum, stainless or mild steel.
I have not seen any of the pseudo reproduction metal dashes yet, but have heard that the bracing and/or mounting tabs are not as stock dashes (or are missing?).
The overlay could be tack welded on before paint (if mild steel of course), or attached with button head screws like I did on Bill's .Looked real clean. I will see if I can dig up a pic...
I did not realize that was you at Carlisle. Saw you for a moment around lunch time and did not recognize you with the sunglasses! Then someone mentioned later that you were there.:-[
