KitchenAid Superba Gas Slide-in Range Spark Ignitor Problem?

Greetings! As all four burners on my KitchenAid range (KGST307GBLO/9752834A) are no longer sparking (though gas flows), I assume my spark ignitor module has failed. I found this through all the wonderful forums online. What I am unable to find, though, is the location of the module, and how to disassemble the range to get to it. I have manuals and tech sheets, but nothing that shows where things are. I tried some disassembly to see if I could find it, but could not get very far. Many thanks for any assistance!
