Is there any consensus as to the internal organs/stuff which maybe doesn't fossilize well? Like, did they just evolve a bitchin' chassis but they're constantly tinkering with the internal bits?

They would most likely look the same but there are still evolutionary changes deeper in the DNA that aren't visible like metabolic and digestive functions. A modern horseshoe crab would not be able to reproduce with one from a 100 million years ago despite looking virtually identical.
