Ray,
I have worked closely with Scott at SJR.
One of his top concerns is that what ever you do, it be done in a safe manner which does not result in an accident or injury as a result of modifications done to your car. His goal is to provide quality parts for you the builder, but you ultimately are responsible to make sure it is installed in a professional manner. He is fully capable of modifying a steering component and including it with a lift kit, but has purposely chosen not to take upon himself the liability for such a crucial safety part of your car.
The quick answer to your question is yes, most of his lifts are a simple bolt in installation, but to go along with Reveen's comments, there are an assortment of other small issues with your car that need to be understood and addressed and this is best done by someone with knowledge of the components affected. When you do the installation, you need to have someone on your team who understands the factors and has some small fabrication experience.
For a modification this large, an inexperieced person can not expect to drive the car into the garage, follow a step by step instruction sheet and drive back out ready to go in a couple hours.
I hope I haven't thrown cold water on your project.
Good luck
Rollie
