I haven’t actually seen one in the flesh, but I think the D2 pointer is a part of one of the sheet metal fold up locks under the head of the fasteners holding the clutch housing to the engine cylinder block.
In your case I think it’s the lower straight edge that you’ll use just because that seems to be centered in the round window. Might be a good idea to verify TDC marks and cylinder numbers before you start. There seem to be quite a few flywheels that are installed wrong and that causes a lot of grief when you don’t realize it until you’ve already adjusted the lifters and then tried starting the engine etc.

CCjersey , won't it be great after the forum upgrade .Won't be able to see the photos to be able to help .
as ccjersey said it is made onto a fold over lock tab for the flywheel housing bolts however it doesn't seem to be very "accurate" but that is just how they are. check out Toby's squatch253 on you tube under playlist caterpillar D2 5J1113 then you can see how its orientated
