I agree with you guys on the pilot needle bearing vs. the bronze pilot bushing. Needle bearings are better for racing applications only.
The bronze bushing you are installing is supposed to have a very, very tight fit, so do not freak. You are putting it in correctly.
Having a bushing installer tool is good, but not absolutely necessary. When you are installing the bushing, without a bushing installer tool, make sure you do not distort or smash the inner hole on the bushing.
One thing you need to remember, the most critical part of a clutch job is the proper alignment of the clutches to the pilot bushing. It can make the difference between cussing and spitting, or having a big smile on your face for a job well done. Make sure you use a line up tool. I like a splined line up tool better than the universal cone types.
