I have a T5 from a 4 cylinder that I am going to put into my 5.0. Don't dog me on this, it's a SSP coupe that I am putting back to stock and will not be getting beat on. The tranny is perfect except the previous owner did not grease the bearing rertainer and it's now damaged from the throwout bearing. I noticed on summit they list 2 different bearing retainers, which one do I need??? I am thinking I heard that there were differences between world class and non world class. the trans came from a 93 model car.
