Prochargers are mounted on a thick aluminum plate, some times two thick plates. They bolt on with only a few bolts. The Superchargerstore should have pics or do a search.
When you order from Procharger they build each kit custom. And it can be as complete, or if you decide, it can be a tuner kit.
When I opened my kit it had everything you needed to put it on my SRT Challenger. Including a real nice instruction book. I was really pleased with the install. It was easyer then installing the TTI headers on the same car. I did both.
If you call them they will set you on the right path.
This is my only pic.
