Hello tlorber,
A few weeks ago I went to my local
Applied Industrial Technologies store and purchased the bushings I needed for my steering box rebuild and they were dirt cheap! I took in my old bushings and they measured them and ordered replacements which I picked up the next day. They probably even have the oil seal also. This is their website:
www.applied.com Here are the offices near Los Angeles:

Good luck!
P.S. - I wish I had known of your bushing extraction method a month ago!
