I have a 2003 209 CLK55 and have just had the geometry checked. They said it needed camber and toe adjustment.

Can somebody advise what I can adjust from the factory and if there are any parts I need from the dealer?

Grateful for suggestions.

Update:

i have discovered that the car only has toe adjustment from the factory, however, it looks like the rear toe adjustment bolts on both sides are seized.

Is there an easy solution or do I need to replace both arms? The car drives well, I am tempted to leave it until the arm needs to be replaced for the bushes.
