Well I hope my tank search is over. I went to three parts yards and brought two tanks home. They both had pin holes in them and did not fit real well. I just finished my engine and decided it would be stupid to put gas from a dirty tank in an all new engine. I measured my space where I wanted the tank and then spent some time on ebay looking for a new tank. A lot of the adds give the dimensions of the tanks. A tank from a 70's Jeep was just the size I needed and found a new one for $49 + $30 S&H. I hope to get it next week and will let you all know how it works out.
