So had a check with Dynodaze again, in light of that compatibility list, and asked for Rich to confirm, (although still not 100% sure the response I got was from Rich) the reply I got from them was them saying that coilovers for MB's use EK fork in the rear, so they say it would be EK LCA's that go with it.
So fingers crossed I won't have to return the EK LCA's that I bought.
