Going to go with oem bearings as the other were all race tri-metal bearings which I don’t intend on rebuilding anytime soon.
Bottom is lower bearing.

I'm curious about what oil weight you run and why the oil pump was initially replaced? I run 0W40 Mobil1 since I bought it with 65k, currently have 135k of hard miles...trans gave up and had to replace that, but I digress. I ran my VIN on RealOEM and my oil pump is the 3256 already but I've got a 1/10 production date vs you saying your car is a 2011.
I can't recall dudes name now on IG, but he does S85, S63, etc complete rebuilds and swears up and down about King Bearings and running Redline 5W50 which isn't readily available locally unless I order it online vs Mobil1 @ Wal-Mart.
