Let's make it a bit easier guys to get no problems
Here's a picture i made from the cover i have on the left side of my LHD car:
As i look at the pictures you've made Indy of yours it looks exactly the same as mine

so this should be a near side cover on a RHD as it's nearest to the kerb imo
Question here i think what is the near side and what is the offside on both cars LHD and RHD,best way to avoid problems is not to use offside and nearside but left and right as this is in both countries the same i believe
My point of view is that i need the 642 for the right side of the car were your steering wheel is located which is the offside i believe,O for steering wheel
Any more info is welcome guys,maybe i'm wrong.......
