    Realized that Toyota part number for the Vacuum Switching Valve, 90910-12274 shows a equivalent Denso part number MX184600-4550.

    When searching for that Denso part number, you can find a similar looking valve with Toyota part number 90910-AC002.

    There are a lot more used parts on eBay for 90910-AC002. I may give that a try.
