What Throw out bearing system are you using with your G3?

I'm looking at the American Powertrain hydraulic throwout bearing (HTB) for my four speed conversion. Not cheap but from what I've researched it is a good unit and I would think it should work with a G3 if you are using a stock bellhousing and A833. They have kits for A, B, and E body cars with several different transmissions.

The master/slave was another option on my list. Can you share any details on what you used on the other car. PM if you don't want to clutter this thread up. Thanks.
