Sheared off the hanger bolt on my X01 rear der and got the b-bolt kit to repair it - newer style with no wave washer, just an o-ring.

Can't find anything online regarding the replacement, but it seems straightforward. Just not sure if I should grease the bolt inside the sleeve a little and which o-ring in the kit to use - I'm guessing the larger one (seems the best fit to seal that end).

Anyone have any helpful hints before I just throw it together the way that looks correct?
