Ummm, 8 year old thread, dude. I doubt he's going to be getting back to you here, so how about a PM to the guy directly?
Don't count me out just yet! I have attached a .DXF file (generic 2D CAD file used for water jet cutters and laser cutters), and also a .DWG file (AutoCAD 2D file format). Find someone in your area who does laser cutting or water jet cutting. Give them the .DXF file on a thumb drive and tell them to cut out 2 for you. My local guy will do these for about $40-50. You can also just print the thing out at 1:1 scale, cut it out, and use the drawing as a pattern if you really want. I made mine out of 1/4" plate steel but there's nothing really sacred about that size or material. You could go to a thinner steel, or switch to aluminum. Obviously this would cause a change in weight, strength, and cost depending on what you choose. Let me know if these don't work for you, or if you need something different to get up and running.
I also ended up making my actual strut bar that attaches to the plates out of round DOM tubing. Let me see if I can find a picture of what I ended up with....
