Yes, there is a hook tool, but as I said, in the W123 you can usually remove the cluster easily without one. Once you loosen it the cluster usually pulls right out. You can also snake your hand up from beneath the cluster and push it out from behind. In some models the hooks are absolutely the only way to get them out, but I've never needed them on the chassis he's asking about.
