It's for both, and the shipping estimate is from Uship.com. Actual shipping could be more or less, if you find a better quote... by all means go ahead. The shop will take care of packing and get it ready for pick-up.
The teardown has already begun and the new axles have just came in. To those of you who asked for pics (axles, header, exhaust, etc) I'll post them as soon as I get them.
4" similar to OEM width, shipped for $150. They are in good condition, with no crack, bent, or dent. However, I had them spray painted matt black to match the body and the paint is starting to peal off.
