I had to use 3 u-joints to clear a big block that was moved way back, though my preference would have been to use 2. I recommend using quality u-joints, keep the u-joint angles as small as possible, use a well mounted carrier bearing as near the center u-joint as possible, and make sure the u-joints are properly phased. In the picture that I have attached, the center support bearing is not installed, but you can see the mounting tab just below and ahead of the center u-joint. Good luck.
