I had a topic a few weeks back asking all these questions because i was confused what from my truck i use and what from the donor 3rz truck i would use. And i was told i needed
w59 slave cylinder
w59 clutch fork
And complete 3rz clutch kit including throw out bearing which im guessing is also for a w59.
So yes i am running a 2002 3rz with w59 clutch, pressure plate, flywheel, slave cylinder, clutch fork and throw out bearing with a marlin r151f to 3rz bellhousing.
