I would try to find a way to make it work without a hydraulic throwout bearing.

Unless you enjoy removing the drive shaft and transmission to replace a leaky cylinder. And if you have a torque tube rear axle it is even more fun, as the rear axle or springs have to be unbolted to allow the transmission to be removed.

Who ever though of a hydraulic throwout bearing should be forced to replace every single one that ever failed.
