Yes, there should be a kit from the dealer. One big O ring, one small round seal and a new spring clip, IIRC. I think I ordered mine from Mancini.

It will be a standard size. Take the old one off and
carefully measure the cross section for thickness and the outside or inside diameter. then go to McMaster.com and put in the specs, you will have your order next day.

The O ring is 1.750" OD by .100" thick.

I got a kit for my Roadrunner from Yearone. It had the large outside O-ring, and inner seal. Didn't cost that much either.
