I have a 2000 z28 with the t-56 tremec trans. I am replacing the clutch and I noticed that the throwout bearing that came out is different that what the parts store supplied me with. I've double checked the timken part # with a few other parts stores and its the correct one. # 614174. What could be the problem. If the pic works, the old bearing is on the right and the new one is on the left. Please email me and I will send photos.
