The kit (really its pieces and parts that you order together) is available from ARB AU and US. 100% of the distributors I have found of ARB stuff either don't/won't carry suspension components or definitely don't even have the part numbers in their computer inventories. I ended up googling Nissan Suspension and going from ARB's own dealer network and finding a place in VA or NC that deals with OME stuff. I got all my part numbers via e-mail correspondence with ARB AU. And when I placed my order via phone the guys called ARB in washington to verify the part numbers I was giving them and that the parts were infact in stock. Everything checked out good. I highly recommend http://www.4x4connection.com
for ordering the parts. Prices were cheaper than the nearest shop that could order arb stuff for me even after shipping. Good bunch of guys (I think only 2, John in the morning and Chris in the afternoon) and very polite/customer service orientated unlike others I've dealt with. Plus shipping them saves me a horrendous drive to get them.
IIRC it was like $63 per coil. I know the whole kit came out to be $737.76 shipped. I believe teh struts were 120 and the shocks were 80 each. I just can't find my notes right now on prices.
Just found the prices. $62.95 per coil, $84 per shock, $120 per strut & $77.96 for shipping the 84lbs of love.
