Who's fabricating the new piston rings, bucket tappets, and lifter springs that will be needed to withstand the higher burn temps of ethanol?

The easiest way would be to pull the engine and replace it with a more modern truck engine of comparable power.
Now, note that I said "easiest", not that it would be easy. It would take a well-equipped garage and a knowledgeable team to do so. But it would probably be easier than to locate working antique replacement parts, or get the specs to some mechanical artist with a well-equipped machine shop to make them from scratch.
