I'll weigh in. I understand the concept of the slots. I have access to a complete welding/machine/fabrication shop that has helped me immensely over the years. (I used to work there, still friendly with my old boss. never burn a bridge). The shop has everything you could think of Amada brake presses, shears, turret punch presses, lathes, saws, plasmas, laser cutters, From a Cincinatti 300 ton press down to a Beverly. I think a CNC Bridgeport could do that but it would be one heck of a program. Could be a NASCAR part but still... how did they do it? I think one company somewhere (not GM) did it for the aftermarket. I think it was stamped in before being formed. I had another friend that worked at Art Kraft Machine in Langhorne, pa that could have did something like that.
