I got the column all rebuilt using as many new parts as I could track down. MegaParts had some of the parts and they had a cool little bearing puller and press combo that was value priced. Detroit Muscle had the other stuff I needed. The turn signal harness must have been original since it still have the part number on a paper tag. I'm surprised that paper tag lasted 50+ years.
