The Guitar Gallery Forums - The Guitar Legacy of Matsumoku

Hi guys, i'm ne here and i'm a bigt fan of matsumoku guitars. I've just bought a nice used '77 AE-650 aria MACH1 guitar but the bridge miss some screws and one of the "string holder" on it is nylon and after a while there are tuning problems in that string. The ideal would be to find the missing parts but where i can find that?
i've tought to buy a new bridge on some on-line store (want to buy the witch hat knobs too to give she the original aspect of the '70).
ths is the link of the catalogue:
