Good luck with that. I got lucky when I found a pair of them bearing cassettes in a junk box someone had. The bearing is loose in the carriers and don't know how to tighten them up. Not for sale. I have an 05 Tempest and they told me the same. I want to experiment with caster by changing the oval pills. They can't help with anything for these old chassis. Millenium Chassis are not on my shopping list.
