[C320-list] Mast Plate / Compression post - 2007 Mark II

[Charles Holbrook]

 Jim:
I doubt I will be much help as my boat is a 95' but I was able to remove my compression plate.  The plate was welded to the top of the post and everything came out as one piece.

 Hi,

To add to the confusion, I own Hull 1122, Mk II 320 which was sold in 2007 is Sydney Australia. I have the original sale documents all executed in 2007. 

I bought it as the 3rd owner in Feb 2020 and relocated it to Auckland, New Zealand. 

So all very confusing.
