While we're at it, don't forget to keep your tank topped up with ETHANOL-Free premium fuel.  The less air in a tank, the less room for moisture which condensates and then settles to the bottom of the tank.

NPD is selling tanks that aren't galvanized, but they're not bare steel either. They have tanks (not this one) they are calling concours, don't know what that means to them.

Aren't there at least 2 capacities for the 65-'73 model run? I thought there was a 19 Gallon tank too?

The OE tanks were 16 gallons.  They make replacement tanks, that have a raised top that hold more (22 gallons I think).  They require
a shorter fill tube.  If you're not worried about originality, you could go that way or even order a stainless tank.  I have one in my
current project. It's much more shiny than the original, but will never rust.

I had a similar problem and it ended up being the Ignition Condenser.
