Looking some help please. I have a Radtec and Audi OEM oil pipes to get fitted along with coolant radiator and AC condensor

For the oil cooler there is a bracket and the bottom of the slam panel which supports the oil cooler however mine is rotten and I am trying to get a replacement.
I have attached pics, however when phoning the stealers the bracket is not on the slam plate?
The part number on thebracket draws a blank but as it has its own number surely this should be found or am I missing the point totally!
Anyone here been in this situation could share their opinion please.
TIA
