Those that have and those that will.

Good tip about the magnet. But I didn't have too much trouble capturing the keepers after removal- in fact, one fell to the floor but was an easy find.
What was tricky was putting the keepers back in place- even with another guy helping me. I think we put some grease on the keeper halves so they would kinda stick in place. You definitely want to be sure they're in there right!!

Here is a tool Aircraft Spruce sells that is similiar to the ones I saw at the convention. I think they sold for $20 at the convention. I should have bought one.
