XK half shafts

[07JeepXK]

OK I'm looking at replacing my half shafts. On RockAuto.com the right has 1 option so no brainer there. The left is either w/ or wo/ limited slip differential. My question is how do I know what I have? Is there something I can look for to see if I have limited slip? I'm hedging towards the wo/ option as mine is a base model but I could be wrong. Thanks for any help.

That's easy. To start what engine do you have? Do you have the t-handle by the shifter to engage 4 low? Does it say Quadra Drive II by the shifter? How many bolts is your rear diff cover. If you can answer those questions I can tell you which drivers side cv shaft you need.
