Theres a plastic brace that hold the top of the grill to the bulkhead. it clips into the grill and bolts to the bulkhead, and the bulkhead cover clips to the bracket.
the original C250 bracket is too short and also not wide enough to fit to the CKS grill.
I have spoken to CKS and they say this is just how it is...
I'm assuming the bracket is different for the different models eg. C350(twin air inlet) so want to know if anyone else has had this problem??
I wonder if your dealer replaced the bracket with the correct part?..
I cant see the chinese fabricating these grills with a different fitting arrangement... it must be a replica of an OEM part! Just need to discover what bracket is needed!
I'll try and get some photos this weekend.
