Hi Mark,

I punched in the part # XXXXX the site that you sent me and that part # XXXXX not exist

any suggestions?

Ok, I tried some other numbers on their site......and it seems their site might actually be down.


The number I gave you is a good number and they are about $11 through your Dodge dealer.........or maybe try that site at a later date if you want to go that route.
