    Try checking the junkyards around your area for a used one to swap it with. Maybe craigslist or ebay/used?
    If you have instagram check out @jp_parts
    He is on facebook (lingers around the protege pages) as well.
    98% sure he'll be able to find one for you. I just ordered roof rack delete strips from him, he'll likely be able to get what you need.

    The non-fouler trick will get rid of the P0421 code.
