My 20 year old aluminum tank had developed a small leak from stress crack so I opted to go with a new Moss steel tank rather than patch it again. Moss said they build their Classic Gold tank to be a perfect fit replacement with no problems with the fitting connections or size. I have to agree they did a great job of replicating not only the fit but the look of the original. I want to give credit to any company that spends the time and money to build parts for these cars and makes the effort to do it right. And at a price that was hard to believe. I think this tank will take me as far as I'm going in this car.
