I have a 1979 that is missing the dust busing causing some play in the steering wheel. I found on this forum, but can't find now, where someone had taken a early 1980s urethane suspension bushing, drilled it out a bit cut the side and slid it over the shaft into the hole to fix the problem. Has anyone else tried that and did it work? Also any idea what size to make the hole in the bushing so there the shaft goes through without a lot of rubbing? Or is there another way to fix it? Is the OEM part still available? Thank you for your help.
