Any forum members experienced working on the N73 V12 engine?

I'm doing a top end refurb on my 2006 760i and noticed the brackets shown in realoem that help support the intake plenum (there's one on each side) are missing. It's not clear to me if they were ever there or not nor how they are mounted. They are mentioned in the service manual. I was hoping someone on the forum might have pics or experienced this themselves?
