It's a JK my jeepin' brothaa. I have an 09 X.
Easiest and quickest way make the distinction between the 2 models is to look at the turn signal lights. On TJs look for the square ts lights on the front of the fenders and also the side turn signal lights look kind of like an upside down check mark. Our JKs have the round signal lights below the headlights and small round ones on the side of the fenders. Oh and from what I've read, there's really no rhyme or reason to the designations of YJ, TJ, JK. Some one that was obviously a die hard TJ owner once wrote that JK stood for "J'grocery Karte".
That said.....Welcome to the forum!
