Nacra 5.2 mast innards

Hi all,

I have dismantled mast base of Nacra 5.2 and found rubber band inside of the mast. The attachment hooks have rotted of and it didn't seem to hold anything. I do think it was not doing anything vital, but maybe I could fix it while I'm at it. The only plausible thing for it to hold i think is rotator arm bolt inside the mast.

Am I thinking in right direction, should I do it at all or can I just put back mast foot without putting rubber band in.

Sorry forgot to make photo of it, but I hope I have explained clear.

Thanks.
