Guide for replacing old hydraulic lines

I slide the retaining clip out and removed the pipe/line and seal. The seal looked fine. I did notice that the retaining clip seemed to be 'flattened' so it was retaining, but not providing an axial force. I used a small screwdriver to open up the clip so it provided a stronger wedge. It took more force to reinstall but the leaking has stopped. Time will tell.
The leak is back. I would like to replace the seal. Does anyone know where to get the seal?

I swapped the seal with one from the other side and there is still a leak on the driver side (left side) so it looks like the seal is not the problem. I don't see leaking from the rod seal so I think the hydraulic line must be leaking at the swaging. Looks like I will be replacing all the lines.
