Old MM Floyd Rose replacement

I am owning an old Silhouette with Floyd Rose. Now the blocking mechanism for the strings on the bridge are not correctly working anymore. So I am trying to get spare or replacement parts. Or may be replacing the whole system. Everything I have tried failed. A Gotoh Floyd does not fit, Gotoh saddles do not fit. Even the small lock inserts to fix the strings do not fit.
Sorry but I have to say that MM designed scrap at this place. Does someone have an idea?
