The install only took me 2 hours. All that you really need is a socket wrench, a couple of sockets, and possibly a second adjustable wrench (or similar) to hold the nuts while you're tightening. In my case, I used an air socket wrench, but no other special tools required. The kit comes with all the brackets, nuts, and bolts that you'll need. Instructions could have been better, but I didn't have to refer to them much, anyway.
Seems that www.autoanything.com no longer lists that part on their website. I ordered them only about 2 months ago. Perhaps you can call their 800# and ask to be special ordered.
