slick way to mount sliders

I also notched the frame just not as deep. my frame was previously boxed when the springs were moved in. I added the sliders to lower the car and help with issues I was having from the spring hitting the end of shackle travel and unloading the suspension.
sliders are the only way to go in my opinion. the car left like an animal after the install.
only wish I could have done a back to back test.
