just search for a trim fork. if your carefull u can get away with a flat blade. but in all honesty by the time u have fecked about taking liner off, you could have bag changed! its not worth it for 2 little spring clips!
Feck it looks clean in there
Ive seen cars with only a few hundred miles on then with more muck than that!
How long did it take you to clean / paint all that?
