Some choices to make.....
I am not aware of anyone rebuilding these sealed units.
First option is to clean them up externally and re install.....for the amount of driving you will do they will be fine.
Second option....cleanup/wirebrush the shock body...... you may find the Gabriel part number........ Gabriel still makes shocks very similar to yours. You will need to match the eye piece size and the length compressed and fully extended..........
Good luck
