Sort of a sad story. I replaced the tank in my 69 Z-28 in the late 70's. I still have the tank, I checked it awhile back and there is what appears to be about 3/4 inch of a broadcast sheet stuck to the tank. I would imagine when I pulled it in 1976 I looked at that weird piece of paper and pulled off what was stuck and threw it away! Didn't know what those pieces of paper were back then, but what to heck it was only a $2350.00 dollar car.
