Having looked at all the dimension info I can find, the Floyd Rose ones won't fit. The routing at the back is not long enough for the original, and the block is too deep. The Pro has narrower string spacing, and again I think the block is too deep.
The Gotoh one has the same issue, the block is too deep at 41mm, which would foul the back cover. The one on the guitar is only 30mm.
It looks at the moment that only a similar Schaller one will fit, providing that is that they haven't changed in the intervening years.
