I have found NOS bearings on eBay two times for reasonable prices. If you
keep a check on eBay you might come up with one. My MOSS bearing lasted
about 1000 miles before it crumbled in it's casing.
And on another note. I have had two back surgeries and I was told after my
last one (5.5 hour surgery with lamina removed over the lumbar spine) that
I would also need to come back sometime within the next ten years for
I dread the fusion part. . mainly due to the recovery process that I have
heard about. You have to be in some type of cage type thing so that you do
not move around for a good while?
I wish you all the best regarding your surgery.
