Lucky me.

The half shafts that I got from a junk yard had the diff brackets still installed. A guy at work is trying to set up his own welding shop & is willing to give it a shot.

As soon as I dismount the xtra brackets, I'll get him started on those. Then I'll get him to modify the ones from the Proton as soon as I pull them off. Don't be impatient (I am the king of procrastination) but I'll make them available to the forum & keep the cycle going.
