Parts like this are not discontinued, the dealer may not stock them and the Chrysler dealer may say that it cannot be got but many such parts are used in many cars and were not made especially for our cars. These parts are shelf items under there own part number and are easily available if you use their actual part number.
Ala_xfire is correct in his post, I purchased a couple when I got my spares of this part, you should do the same.
