you can also use arrowheads, with concavity set to 50% and length set to 2000-3000%, but clone stamp is easier.

Oh I see now. Thanks for the help!
Clone Stamp should be enough for this one, but if there was less to work with, you could always recreate the lines by yourself:
1. Open an empty layer.
2. Outline the speedlines with Pen Tool (not just the missing parts - everything).
3. Fill them in with a gray pattern you created or copied from somewhere.
4. Apply a white-black gradient in Hard Light mode.
