Has anyone ever drilled a hole in one of the arms of a clutch bellcrank? We recently tried. You know that scene from the movies: Air Force Base, deep in the desert, high security, big hanger, captured alien craft, boffins attempt to drill into it...... Well, I'm thinking GM bought some 'used' metal from Roswell back in the 50s and made a few bellcranks form it. This thing's nuts. Fancy yourself a workshop whiz? Find yourself an old truck bellcrank and be prepared to be utterly humiliated. Guaranteed.
