This is a very long thread with all kinds of information and opinions.
But the simple answer is no, use you current bell housing.
The easy way with out a custom bracket is to get a Wilwood Type (there are a lot cheaper ones out there) "puller" slave cylinder.
Take the rod off the back, and the rubber bellows off the front. Stick the front shaft through the hole in the Bell housing (put there for the clutch cable). Get a (don't know the name, but it is a long bolt type thing about three inches long that will screw on to the end of the Wilwood shaft) then attach the shaft you took of the rear of the Slave. It will screw into the "nut" thing. Then attach it to the yoke. It is really very simple. The slave is held in position by the connection of the shaft to the yoke no bracket needed. I will try to post a picture which will be worth a thousand words.
I would purchase my slave from:

They show two models, the "universal" one has a 1/3 inch greater pull. If you need more that one inch go with that one. The cost is half the Wilwood.
