Last year I called up Off Road Design, with lots of questions about crossover steering. The owner of the shop, Stephen, spent about 30 minutes talking to me, explaining the process from start to finish and answering all my questions. He spent that amount of time, without knowing if he was going to make any money, I thought that was pretty good customer service. I ended up ordering the crossover and high steer set up from them. The quality was incredible, the parts all fit togehter perfect.... I couldn't find anything wrong with the process or the parts. This was my first time diving into something like this, and it was actually easier than I thought.
As I find steering to be semi - important at times, I would say to go with tried and proven parts of known high quality. Cost a little more maybe, but you put it together correctly, and you will not have to mess with it again for quite a while. You can see the arms in my photo gallery if you want.
