I think he is talking about the diamond wire spreader bar...right? I would not think that they would be to expensive but the repair might be tough.

Check the rudders and make sure all the system is in working order.
Depending on the year it might be foam core or solid laid fiberglass. My 5.2 is solid and really stiff, but either could be bad or good.
Just check the normal things, sails, tramp...etc.

Check the mast step, see if the ball has been changed out to the newer style or if it is the older style. Finding the older style ball can be really tough and if you can't it is about 100 dollars to change out to the newer style because it requires a new mast base and a new dolphinstriker.

That is about all I can think of right now.
