I used the stock K member and all I did was notch the bottom of the frame until the K member fit in from the bottom. I had to check, recheck, and recheck the ride height and levelness of the k memeber front to rear and side to side. The member is flat, and at ride height the A arms are almost level and paralel so this easy but time consuming. I had to build a pair of adjustable stands to hold it all up off the ground while checking and rechecking EVERYTHING. The only thing I did that I wish I did differently was the frame notch for the sway bar and rack. I went way too big and I could've done a smaller notch if I had built new sway bar links and routed under the tie rods rather than over. That's why I reused the brace that comes off the K member and ties into the front frame horns. It should add a little more strength.
