Their was no stamping they roled 3 creases in the middle for streanth.It was a flat peace of steel and was bent to go over the center brace and that is were it stoped.He did sell the back part as well I didn't get that part.The front cab mount was welded together like a tapered box.I did see in one of these books of aftermarket parts they are making all of it.I don't know if it was him or someone else making the parts.I will look into it.If you like I can send some pictures of it.
