I bought all the parts and a friend installed them. You may not need the springs - as it turned out, even though I was riding on the springs for about three years, I didn't need to replace them. Make sure you buy the boots for all the struts you replace. The blue KYB plastic boots did not work - I ended up reusing the black strut covers on the front and used the KYB long black strut covers that cams with the brackets. Once you get access to the nuts/bolts on the back, it is very easy to remove. If you are replacing the rear struts, oull off the side panels in the rear an then slide out the shelf. From there you can access the rear strut bolts.
I think they stopped making the TRD rear sway bar. You might be able to find one a dealer is trying to get rid of......
