Part I.D
Mopar parts giant is a actually a Chrysler dealer. They have integrated a Snap On parts catalog to their website.
They can only get a part if it's available from Chrysler and not NS1.
Basically, if they have it, it can be gotten from your local dealership.
The P/N you're looking for is NS1 and no longer available, no dealers are showing it on the locator. If you can find one from ebay, that's your best bet.
