Can you post a picture? I thought all the sizes of trucks used the same cluster and it has arrows for the turn signal lenses. My 58 and 59 are both 3200s, so I could be wrong about the larger ones using the same cluster.
Edit: Do you have a GMC? Because they were a very different animal. If you do, I would recoommend specifying that in the post title.
