I have two Pros that came with 3TTT stems and GB bars. On the '73 track bike, the ears came together and the bolt actually bent, in order to tighten up against the bars (came from the factory that way, and the bars and stem were road models). On the '74 road bike, the stem developed cracks across the top of the clamp, which I attribute to the size mismatch. The later bike came with a hex key clamp bolt, the earlier stem had a hex nut.
