I posted some pics of my Delrin bushing install at:
I used sandpaper wrapped around a deep socket to size them. It was slow going, but it was free with no play. You also need to be mindful of the long bolt fitting. The first one I did, the bolt didn't quite line up. I was able to work the outside of the bushing to get the bolt to fit without binding. When is was all done I had no fingerprints and a blister on my thumb.
