Jesus what a f**king nightmare bro.
How do I know I have a KK? Well, it's printed on my f**king reciept, and it feels a hell of a lot better than stock, and I trust my shop because they only work on mustangs. Other than that, I have no f**king clue, and it kinds of irks me. I wish I could help dude and the only advice I could offer is only buy from QUALITY SELLERS - **** is way too shady my man. Good luck though, seriously. It sucks.
