What Are You Doing To/With Your Car Today?

Pulled the gas tank, dumped out the very bad, rust-infused gas. Found that the tank had been restored once, in the past and all the coating is separating from the inside. The car sat for a long time, and apparently it was right after someone had dumped a ton of time and money into trying to get it road-worthy--has a new sending unit, too. Bottom of the filler tube is heavily pitted by rust. Anybody have a source for new tanks for a '64 Dart?
