But I'm pumped to put them on!

EDIT!: So I ordered them through AM. And it turns out they are different enough to cause some fitment issues vs the 05-09 according to Jim over at AM... So I have to wait another "2-3 weeks" becuase Borla has yet to fulfill their order for them... which sorta sucks, but at least I'll be getting the correct part I spose... So yes, for 2010 stangs the part number is the one above for borla stinger axle backs.
