Rod bearing confusion

[Jay Whitely]

> The part number ends with the bearing grade.

***Now, I am really confused. I ordered 4 grade 1 and
4 grade 2 rod bearings. That is what I got. 4 of them
had a black mark on the edge (grade 1) and 4 of them
had a brown mark (grade 2). They all had the same part
numbers stamped onto them, 12111 1N500. That is where
the confusion lies.

The JDM Silvia bearings all had the same part number,
12111 60J00. 4 were grade 4 and 4 were grade 1.
