Need to fix this.

[cribfiller]

Hi all, I have a 2002 base model and over the weekend changed fluids, cleaned and waxed and ready to put in hibernation. However, in the process of wiping down the interior I broke off the little knob adjuster on the cluster. This is the one that controls the dimming of the lights on the cluster. I obviously want to fix this, any help with the process would be appreciated. I have searched the forum and found lots of discussion on replacing the cluster but nothing on this item, thanks.
