Making good progress on my pinion support.  I purchased some more steel yesterday, and set to the task today.  In my attempt to maintain the  "bolt in" aspect of my project I designed and began the fabrication of brackets that will use the back side of the front leaf spring mount to hold them in place.  Basically the bracket slips behind the front mounting bolt, up against the inside of the frame and provides tabs for a rubber insulated cross bar to bolt to.  From there two pieces of square tube will tie the the front tie bar to the cross bar and provide a mounting location for the trailing arms.
