yes we have. and Kennedy actually has these 2 things in place. he was able to ge the skid plates back on, but according to him, he had to bend them around the dropped diff and bolt them in. so the diff sits directly against the skid plates. i don't know enough, but that doesn't sound that good to me. but i don't know. i personally will not be putting that lift on cause the skid plates are more impportant for me. i'd rather use the upper a-arms and ball joints from calmini or AC. once i get some money is when i will decide that part.
