Classic/Antique Car Repair: 66 ford ranchero, Fuel tank

Question
where can i get gas tank are tanks interchangeable with something

Answer
My stock answer for “where can I find….” Is to latch on to a copy of Hemmings Motor News, the old car hobbies classified bible. There are many companies that supply parts for old cars and you will find them in Hemmings. www.hemmings.com. And for the most part fuel tanks are not interchangeable with other makes, models, or years.
