I designed it, built a jig out of plywood and L brackets (I just came across it moving stuff to my new shop) and had the guy that welds my K frame packages (Fog) tig it up for me.
there are pictures of it on the first few pages and thru out my HemiDuster build thread good picture on page 2, post 28
