Speaking of which... I received my replacement part some 5-6 months ago, but as carpet season was over it sat in my pitbox until now... So I decided to change it before the new carpet season and found that the replacement part is actually completely different, it's the regular RR not RR+2 as on the newer cars. Is that what everybody got, or did I just got "lucky"?
