I'd be interested to know how you make out...
When I sourced out the OE speed control kit a few months ago for my '05 (P/N 82207313), all the online sellers I contacted (not e-bay mind you) did not have it in stock. One I called (a Jeep dealer) in the USA, looked it up in his computer and told me it was discontinued, and there was ONE in the entire USA, in Texas.
I phoned my local dealer, who also said it was discontinued, and that there was ONE in all of Canada, in Nova Scotia.
I swear I'm not making this up
I had them bring in the one from Nova Scotia and install it for me.
Good luck!
