As he said, STAY AWAY!
I tried to install one of these POS, and had nothing but trouble. I ended up sending it back and after some "negotiations" only lost about $150.
I asked them for recommendations for which headers would work, they told me which set of headers they used for development. I contacted the supplier and was able to get the exact set of headers used on the test mule.
After installing the rack, then the engine imagine my shock when the header laid right on top of the pinion shaft of the rack. Not even a chance of making this kit fit. They thought I had assembled it incorrectly, but photographs showed that was not the case.
I now have their manual gear along with a Shelby quick steer kit and other aftermarket parts. Very happy with the setup.
