Earlier and current sleeves retained; both sit correctly before closure in the maintenance comparison, then one finger makes contact first. The fingers have matching face references but their backing stacks look different

Have tooling establish whether that difference is specified before removing anything. Matching loose faces do not necessarily mean matching assembled contact positions, but the drawing needs to answer what was intended.

Drawing calls for equal backing; one side contains an extra packing piece absent from this job's assembly record. Maintenance is tracing its reason before restoring the specified arrangement

Include the pickup changes in that review. Once the geometry is restored, the old compensations may no longer describe the intended grip, even if they made the uneven assembly appear usable.

Packing belonged to a previous temporary repair, not the released sleeve setup; maintenance restored the specified backing and the programmer is reviewing the edits. The complete pickup-through-release comparison is still outstanding

Keep the replacement instruction tied to that released assembly. A note saying extra packing removed will not tell the next maintainer which backing combination actually belongs there.
