Tool sizes above 24mm on 599 GTB

I'm in the process of supplementing (and adding) more Snap-on tools to my garage as part of the purchase of a black snap on tool box (which seemed appropriate to match the color of my car).

I've been going through the workshop manual and cannot see any real demand or call for bolt sizes above 24mm --- for the technicians out there, what are common use socket sizes above 24mm on these cars?

 

This is pretty standard. I've had a snap-on 36mm 6 point impact socket for years.

I cannot find any reference, visual or in the workshop manual, for a 36mm oil cooler line. I even had my hands on the return lines today at the Ferrari dealer and they aren't even close to 36mm. What are you referencing?
