I ordered my main and rod bearings from an acura dealership in FLA, the mains were fine. But the rod bearings look like they are all tarnished. Also when I compare them to a set that I had around they are not as wide. The package also said p-72 not pr-3. I don't believe that this makes a difference, a b series bearing is a b series bearing right? so should I use these bearings or send them back and get new ones.
