This kit is listed on the Hurst website as being on sale. There is some confusion as to the application year. Part of the listing says it is for 2010-2014 Challengers, but another part of the listing shows it as being for 2011-2014 Challengers. A call to their customer service yielded no definitive result. My question is has anyone used this kit on their 2008-2010 Challenger? If so, any issues?
