Do some research, call the order line and tell them you can get the part for a certain price and they have usually matched or have done better on pricing, at least for me. Then have them send the parts to the store in Tucson. (free shipping) This has worked for me here in San Diego.
As for labor, I've done the same thing but it's only been an Eaton locker install.
The guys at Desert Rat are good and reasonable. They actually talked me out of doing something to my JK that was not needed even though I wanted it. They told me it was a waste of money and I am happy to have them do things I have no idea how to do.
They talked me out of getting Quick Disconnects for my rear swaybar. The position of my lower shock mounts was going to interfere with being able to quickly remove them. In addition to that, the rear bump stops that came with my lift kit do not allow for much travel, we suppose its designed that way to limit the amount of damage to the rear fenders. So I will not need the disconnects until I have changed out my fenders and reposition the lower shock mounts.
I also had bad experience with this location when i wanted to spend over $1000 buying tires from them, anyway i decided to buy them from Discount tire a block down and very satisfied. Actually on that note i am selling the tires
