The first one of those I saw was in the back of Don Garlits 1974-76 balck Dodge crewcab at 1975 Winternationals in the tech line. I commented on how I would love to have that to put in my HemiCuda. He said no you don't it is broken I would still love to have one, it is modular so you can make it fit what you want it to, not sude of the strength though . They didn't stay in the race cars for very long
