[I] wont be able to raise [the mast] until i get the new mast step system[...]
Be aware that it took a month for Nacra UK to get me a new complete mast pin for my 5.2. Be prepared for some wait: it got shipped from the US to Netherlands, from there to the UK, and from there to me! You may be better off ordering directly from the US via this site or via murrays for example...
