what store sells the left handed schaller tremolo, locking nut

[garykeller15]

i have a 1990 charvel lefty 475 metallic black gtr. i need to replace the locking nut and schaller tremolo on it. i cant find no store that sells them only the original floyd rose left handed. i have heard to use a original floyd rose tremolo and locking nut i would have to route(tremolo) and shim(for the locking nut). i rather not do that but. it seems i might if there is no place that sells them. also does anyone know the size of locking nut for the charvel 475 left handed is 1 5/8ths or 1 11/16ths or something else
any help would be aprreciated.
why i am trying to change the trem and locking nut is the the bass of the tremolo is cracked(micro fracture) and bent and the locking nut has deep groooves from the strings. i
