I used Ruff Stuff's weld on caliper mounts on my current project. At first I bought the flat plate type which will not work on the 9" as best I can tell without modification. Anyhow I got the ones that have the bend in them and they worked perfectly on my axle housing. To set them up I installed the axles complete with rotors in the axle housing. I then put my calipers together with the brake pads and bolted them on the mounting plates. Then you can slide the caliper down over the rotor and get everything squared up, then tacked the brackets in place. After that I removed the calipers and axles, then welded the brackets in place. Just remember to position everything where your bleeder on your caliper is in the up position so you can get your brakes bled. As far as the shock mounts if I recall correctly it looked like they would need to moved in some. I used inboard shock mounts on mine so I didn't have to worry about that. I hope this helped with your question.
