You could try Kia. Sometimes they are reasonable for Parts
Or a used one from a Breakers or Ebay
You are unlikely to find what you need listed so find someone breaking an Auto and ask for the Part.
There are Part Finding Services (Google 'Used Car Parts') where you enter what you need and Breakers that have it contact you with a Price.
