Try to find a shop with a Sunnen hone, and a mandrel long enough to hone both bushings at once. That's the best way to be sure they are in an exact straight line. Also check Ebay for a "piloted king pin reamer" that keeps the holes in alignment as the bushings are reamed. I see them there occasionally.
