larger fuel tank for 72 911

[porsche gt3]

Hi,

I am looking for a larger fuel tank for my 72 911. I believe my current tank is from an SC and it holds around 19 gallons. It has the recession for the spare tire.

I heard someone modifies the tanks by removing the spare recession. I assume this would add 6-7 gallons.

Please let me know your thoughts.

Thanks
