I've never seen this before. It's a bracket, with like a pulley (sort of) that bolts to the upper side of the frame just behind the steering gear box. This is on my son's '65 coupe. It was originally a manual tranny (juding from the clutch pedal still in it) and a C code. Was it something for the clutch?
