Based on a cursory inspection of the hardware on It’s Not a Cruise I had assumed the bolts were stainless five pieces and thus not a pressing issue. Recently I noticed that one of the washers was corroding and realized it was likely these were plated steel bolts. Sure enough even though some looked ok from the exterior, behind the scenes they were very corroded. Most of the bolts were spinners because the cone/sleeve interface was corroded in place. One was even clogged with mineral deposits.
Second bolt had to be moved because removal left the hole unusable, the third bolt was really close to a shallow left-facing flake which under the right circumstances could open the gate of a draw and that placement was moved left. The fourth bolt was in hollow rock and was re-positioned slightly right into better rock.
