I’ve just discovered how soft the two black nuts are that thread onto the damper and air spring rods at the base of my wife’s 07-08 Fox Float 32’s. One is fine, the other has a slightly squashed top after using my knackered rubber dead blow mallet as per the instructions. I’ve re-cut the thread etc but still too distorted to go on either rod.

So, anywhere I can buy a pair (and some crush washers too?) Or a part number I can search for?

Mojo has them for sale on their website. Crush washers available as a pack or included in seal kit.
