Need Fuel Tank for 24 Grady

I have a buddy who just bought a 24 Grady WA. For whatever reason, the previous owner removed the auxillary 50 gallon fuel tank. He is looking to replace it while he is repowering and fixing up. The measurements we have to work with are 29.5"L x 21"W x 16"H. If anyone has an aluminum tank that may work, please let me know. It doesn’t necessarily have to be a 50 gallon, but anything 25-50 would be ideal.

i saw a few tanks at bar-mar last week.
