Remember to use jack stands.
And always bring a towel.(go watch Southpark)
Also, pay attention to the orientation of the springs as you remove them, (and put the new springs in the same way) there IS a top & bottom.
They only go in correctly one way.
If you would like some help installing in Moab, let me know, I travel with more tools than many gas stations have, including on-board air & air ratchets etc.
I also have a set of "used less than a year" OME 912's for sale, I told Bart I'd give him first dibs on them, but if he passes, they're up for grabs.
$100 includes 2 springs & me doing the bulk of the install & T-bar crank.
Also also, douche the torsion bar adjusters real good with liquid wrench or PB Blaster before you head for Moab if the install is going to be done there. (No matter who is doing it, they'll thank you)
