Had to take my SMIC out to get at a bolt that snapped inside the map sensor. Absolute PITA and a bit of a nightmare. My buddy had to take an angle grinder to a part of the bolt and slipped, took a dig out the plastic. Only small but has affected the surface of the plastic on the boss. Drilling it out was just as difficult because of the plastic and didnt go great. Managed to thread a screw in just about...another reason to get rid of the unit and get an FMIC asap.
