Narrow "Stock Location" Mount Fuel Tank for 1968 Dodge Dart?

Maybe the later a-bodies are different. The early a-bodies 66 and earlier have the gas tank offset to the passenger side of the car for exhaust clearance.

That's how my 68 is. About 3 inches on the driver side and 1/2 inch on the passenger side. Thinking I may just attempt to narrow a stock tank for now.
