I used an alston frame kit. I left some of the original frame and stock wheel tubs in place, before I cut out where the new frame would go. I did this so the car wouldn't fold on me. Once the new frame was in I cut out the old stuff. I had my 9 inch made by place here local. Dam it was a lot of work, but beat the price for someone to do it. I used coil overs from alston as well. This was put in over 10 years ago now so don't know what kits they even have any more. I did have a guy that I knew do the tin work, as I didn't have all the right tools.
