Glued,but can be done on at least the 126 models poss.others. Saw off with dermal
and small saw blade at parting surface,about 1/2 inch back from face. Pull off cloth
first. Cut only 1/4 inch deep, Reseal with black silicone.
Did this on three Inst. clusters when adding a boost gauge. Clean plastic,repaint inside.

I have four or five 123 clusters. If someone needs one i will sell reasonably. I'd need the number off the face to be sure it is the one you need.
