I have a set of bearings and oil seals for sale. I snagged them several months ago when I was considering kitting my moby 50V, but have since changed my mind. These are not always available, but when they are they're usually $30. Neither 1977 or Quarter Kick currently have these in stock. I'll sell them and ship them within the US for $30.00
The label on the bearings reads:
RLTS+JOINTS SPI ADAPT.
POLYAMIDE JEU C3
