I cant see the detail in those photo's too well, but there are features on that very sad looking chassis that remind me of features on a rail that I had a hand in building and drove occasionally when Ray couldn't, the small block injected 'Sinclair & Little' senior dragster; that flat plate where the four frame rails meet is exactly the same, with the front axle located by four exhaust type clamps. The way the steering is mounted also looks very similar, straight down the middle of the frame to a small rack and pinion. The car was painted green and black. When first put together it had a three hoop cage and no wing, and had a quick change rear, so there would clearly be changes around the back end of the car.
I would suggest Herb or EC get round to Rogers and show him the pics, see if he has any of the build pics anywhere or if he knows where the frame went....
