In my words
Replacement Plastic Cases for 6350-00 is the kind of Pit Hardware part you only notice when it is missing.
A part that loosens under vibration is a part that fails at the worst moment, so thread-lock everything.
Stock on small-batch sets moves quickly, so the listing is the honest source for what is left.

Questions I get about this set
Aluminum or plastic?
Aluminum holds geometry and transfers the hit; plastic bends and comes back. On a rough outdoor track I take plastic in the front and aluminum in the back.
Do I need special tools?
A hex driver set that actually fits, thread-lock and a bench. Rounded hardware costs more time than any part on this page.
