When I did my 9 inch swap it took about a full day. I had an extra hand for part of it. I was able to use existing emergency brake cables. Even used original brake lines. Didnt have to change driveshaft, just install conversion joint. This winter I will make new brake lines when I install sway bar to clear clamps. I went with the Strange housing for the adjustable lower bar and shock mounts. If I could figure out how to uploading pictures I would post.
