Which hydraulic throwout bearing?

is this a certainty? as i am looking to find a replacement one for mine and being in Australia its proving to be a real problem

I've found threads where people have used the clutch master cylinder and slave cylinder from a 1995 Nissan Pathfinder in conjunction with the old style fork/throw out bearing and pedals. I got everything for under like 59 bucks on amazon.
