MAMIYA RB67 proS Spare Parts - HELP ME ! ! !

Hello to everybody! I'm looking for some spare parts for a Mamiya RB67 ProS, specifically some pieces: cocking level (and relative accessories) and main cocking pinion. Camera's (damn!) previous owner forced it and broke lever and its relative pipe fixed on top of the pinion. These are OEM code number I'm looking for: RS 1925, RS 1329, RS 1311 (with related screws) and aRS 1312K2 (not RS 1312K2 of old PRO version)
Around the world could I find an angel who help with my desperate research?!?
Any suggestion will be REALLY WELCOME!!

THIS IS DAMAGE PIC

Hello,
