I just watched thru the whole video, man that is a treasure. Man would I love to do that, a stream liner would be so damn cool. I sat in one at the Dream Machines show and made varrmmm sounds.
I had a belly tank body years ago up sitting on the top of my office in my shop. It was a real body painted red and white with the red being scallops on the front like the So-Ca cars but not done nearly as nice.
But it was a flat head powered car evidence being the three exhaust pipe holes on each side. I have maybe one photo of it somewhere if I come across it I will scan and post it. Damn how I wish I had it now. I forget what I paid for it, something like a hundred bucks and I sold it for $250 as I remember. All I can do is dream that it was one of those belly tanks in the video.
