I plan on taking a some stainless steel or aluminum (if I powder coat them) over to my buddies water jet and have him cut me out some. I need to give him a drawing and he can make anything I want. I am going to have SCARAB cutout for the venting. I'll post pics when I'm. shoud be simple for him time and materials. He can cut anything up to 4" steel, its pretty sweet to watch.
I have the old stainless louvered vents, once I get the initial dimensions he can put anything in for words or script. If your interested let me know, I'll first see how mine work out.
