When I look at my new bearings, Federal Mogul, all 4 of he uppers look identical and I don't see a chamfer as noted in the manual that would be the #1 upper. No red mark either. Should I just assemble and not worry about this?? I looked at the old bearings that came out of the engine, non-original clevite, and I don't see a specific chamfer on 1 of them either. Any thoughts and comments would be appreciated. Thanks, Jeff
