I recently bought a couple of OEM ignition coils for my 4.7 and noticed they have an extra rubber seal/grommet above the o-ring that my old coils don't have. Anybody know if it's possible to buy these rubber seals somewhere? Here's a few pics of what I'm talking about.

 

Check the parts store help section. for something similar

 

No luck finding these things locally in the Help section or on the internet. Anybody know what these seals are called or know of a source?

 

Doesn't seem to be much interest in these seals, but just to answer my own question and for future reference, I found these things finally. They seem rare, not much info on them and are expensive for some reason and aren't available at auto parts stores.

Dodge has acknowledged a need for them on certain Durango models due to a leaking hood seal, they even issued a TSB on the issue.

I found them at http://www.factorymoparparts.com/ for $34.10 for a set of 8. Ouch!
