Magnumforce required a motor plate (they got mounts now as an option).

Control Freak has a website but doesn't show the Mopar product. Mr Norm's GSS Dart has the control freak set-up. I don't like Reilly or Magnum. I talk to the guys at CF at SEMA in '06 and the seemed to be pretty cool.
Call them and talk price.
