pilot bushings?? going from auto to standard

[misschelle21]

hello, I needed some help. My brother in law is dropping in a new engine into his 95 cavalier. The new engine is auto and his car is standard. I was told he needed a pilot bushing he says it is a pilot bearing. I am also told it comes with most clutch kits, but auto zone doesnt have them. I've read on the net all chevy's have the same size pilot bushing. Do you know where I can find it??
