4th Gen clipons fitting 3rd gen forks??

Hey guys,

Just have a question about the clip ons and kill switch, brake levers and such transferring from a 94 to a 90 VFR. I purchased a dumped 90 vfr and the right clip on is broken, the master cylinder is missing and I also need the high/lo light switch along with the clutch lever. I'm having a hard time finding these parts for the right price for a 3rd gen vfr. Would the parts be interchangable from the 4th gen?

Thanks in advance
