I have purchased a FSA Carbon Pro, new, but an older model from 2004. It has the replaceable spider with 74/110 bcd. Is the spider interface the same as Shimanos XTR cranks from 2002 and 2003? Will a XTR compatible spider fit? It looks the same but I'm hoping someone here can confirm.

Secondly, looking for a compact spider for this crank... any hints where I can find one?
