Gitzo Levelling Base GS5121

I just received the GS5121 which I need to mount on my Gitzo 5540LS. In absence of any instructions with the levelling base, I presume I need to remove the flat plate on my 5540LS before I can mount the levelling base. Would appreciate if someone can confirm this?

Best regards,

Deepak

Correct, remove the flat plate and insert the levelling base in the opening and tighten the bolt

Thanks for confirming Bob.
