Hey guys!

Rebuilding a sr20det s13 red top and have came across a little issue.
I live in Japan and ordered all parts from a parts store, they told me when I was ordering to check the color on the main bearings as there are like 5 I believe!

Then order the same color that the engine contains already, I stripped one main bearing to check what color what printed on the bearing, it was green so I ordered green!

I fitted them tonight but noticed the part numbers are different.

Does anyone have any idea why the colors are the same but part numbers are different?

Thanks!
