Thank you for your comments and help.
Ozzy, you are spot on ! I hadn't looked so closely to the sketch, and yes you are totally right, we can see the position of CP9 (as well as the sketch 4.15 page 43 btw
). Sorry...
Regarding the 1 or 2 bolts attach point, I think 1 is OK here in Sweden, but it is good to know how to make it a 2 bots attach point if necessary in the future. So thank you for that too.
Bye.
