Miele fixing brackets for under granite worktop installation

Hi,
we have just had a new kitchen installed and are waiting for a Silestone composite worktop to be fitted. We would like to keep the Miele dishwasher that was here in the house before we moved as it is a good machine and we could not possible afford to replace with one of such good quality

Having just browsed the Installation instructions for this model G694 I noticed it states that when fitting under granite or marble worktops teh dishwasher must be securely screwed to the adjacent units on both sides. For this two special fixing brackets are included in the accessory pack.

We not have have these brackets.

After the ramble now my question?

Are these brackets still available? Or can I use some alternate arrangement to fix the DW to the units.

Many thanks

Lloyd
