i was wondering as to what the axles are that i have? i assume a 30 in front? and a 44a in back right?

what lockers has anyone put on theirs? i see some extra room in the engine compartment that is telling me that i need to get some arb lockers front and back?

i don't think aussie lockers are made for xks are they? i had those in my tj and was about to put some in my wj at the time but never got around to it?

plus i was thinking when i go larger tires, i could install an airtank in that spot?

i do like the idea of getting an extra fuel tank as well? but it looks like an airtank and a fuel tank might be a pretty tight fit? probably not very safe to have those to so close to one another as well?
