Upon checking some old threads, I’m wondering if anyone has good part numbers or a place to call for input and diff shims, along with the bearings for a late 523. I would like to rebuild it and do it once for the long haul. I’d like to make a much nicer video than my previous one too. Any help would be appreciated. I want to get this going so I can have my van in top shape for the summer of 6 dollar a gallon premium gas.
