The instructions are pretty straightforward. Except I don’t read instructions until I do something wrong. My two mistakes ( one was a disaster) 1st was putting the Willwood discs together. I got the pattern off for the wheel lugs on the hub had to heat up to take apart. 2nd huge mistake was I hooked up the pressure side of the power rack to the wrong port and blew out my new shiny power rack. I installed mine with the motor and trans still in the car. I just had to remove my headers.
