Notes:
On the cut/weld it will be done on the driver-side rear cross member pocket. You're creating space for the new cross member. The weld-in plate is just to make the bracket more sturdy (extra support), it does not hold any weight. (used a simple MIG welder for this):
On the passenger side rear pocket you'll only cut the front side, do not cut the back side of the pocket:
The reservoir shock mounts will go on the back side of the control arm, be sure not to route them between the brake lines:
Before and after the lift on the rack:
