Ditto to the above comments! A lot of people who install the M-II suspension kit have little to no understanding of suspension geometry and end up with a job that's less than pleasing to look at in the best case scenario, and possibly deadly dangerous in anything but straight line driving at worst. You'll need to find someone with the fabrication skills and general suspension knowledge to correct the installation errors first, then deal with the ride height and handling concerns with spindle position and spring rate adjustments.
When I was involved with building round track race car frames from a pile of square steel tubing a few decades ago, we would sort out the steering and front and rear suspension with no springs installed, with the frame supported on screw-adjustable height jack stands and chained down to a level floor, before choosing the proper weight carrying capacity of the springs. That process still works today on street machines. Good luck!
