no, you cant do that. yeah, they are fairly straight forward to install, if your ok on the tools, there is a tutorial in the tut section if you have a look in there. only differance between 32 ad 33 is that 32 is hydrolic and 33 is electric, so you have hydrolic lines to block off/bypass on the 32.
also you need to get a wheel alignment done straight away after install. there are group buys that pop up occasionly for them, or just look around on some of the performance parts sites.
