Salsa Fargo and wanting a granny gear.

Look I know all the arguments against going 2x. But I want to go 2x. Is there a place tactually buy the 42/28 2x crankset up that works on the Fargo? I am going nuts with something that 5 years ago I could find almost every where. And now its all one by is great and accessible to all. Please help before I go bald again.
