There's another trick to installing bushings. Whenever I install bushings (and bearing races, too) I put them into the freezer for a couple of hours beforehand. Yes, the shrinkage is minimal, but every little bit helps. Dry ice is even better. (Used to be you could squirt the bushings from a cheap can of Freon to chill them down, but no longer...)

For distributors, I have an old upper shaft that I use. Remove and reinsert one bushing at a time so that when you press the new one in you have the old bushing to guide you. Then pull the other and use your newly-installed other new bushing to guide.
