This may help some guys with tech ?'s. I see alot of questions about what diff they got or do they have LS, or tranny? I had the same ?'s. I called my local Jeep dealer Massey Yardley, spoke to a sevice guy, gave him my VIN. In 5 minutes I had my options sheet faxed to me. Thanks Brian. Tells ya all standard and optional equiptment your jeep came with. Hope this helps.
