I have the reciept with the part numbers at home and can post it if required. The 2 new pressure converters fitted have been modified slightly in design so a new bracket is needed. However its not a must as all that is different is the alignment of holes and the PC can be held on with 1 bolt rather than 2 but for the sake of £15 worth getting a new bracket.
EDIT found the part numbers -
11658509323 CONVERTER X 2
There is also a 3rd EGR PC but thats towards the inlet manifold
