I ordered the Oillite bronze bushings, should get them tomorrow. I think this maybe the best set up also. I had a feeling the needle bearings may damage the shaft. I will double seaI, felt, and O ring. The felt and O ring does keep most dirt/grass out but not perfect. I am frustrated and almost gave up and bought a new mower until I got sticker shock, but most important I love this mower and I want to fix this annoying issue. Will update.
