Rz 500 clutch push upgrades

[Link]

Hi I was wondering if anyone knows of a better clutch push actuator for the rz 500, the cam and bush on mine are very average. I was looking at yzf600 ones and they look very similar and of course are a lot newer. Has anyone tried different ones or found a replacement, I think the older plastic ones seem a less complex thing than the tiny ball bearings and sleeve etc in the Rz one and maybee an rd one would be better even Any help would be great ir if you have a decent plastic type actuator off a yam lying around please let me know. Thanks link
