A little air cleaner "art"

I have been looking for decals or custom tins to put on my 408 stroker air cleaner. I have seen them in the past, but whoever made them can't be found. So, I played around last night with my photoshop program, and used a mix of 383 Magnum tin with one from a 340. It's a first try, but thoughts on the results. If I can get this dialed in, I might have one for the online decal places make one for me.

Do you have the dimensions for the 408 round decal? I believe the diameter is all I need to order a custom 4 barrel decal. Or I can just measure my air cleaner. I am considering 225 on top and maybe Dart GT or 4 barrel on the bottom.
