S Oil cooler bottom hole sizes are different to non-S ?

[bachmoza]

Thanks..
So, whether the two hole sizes may be different or not, but those are destined to align in each hole center axis without leak issue?
Do you possibly remember what sizes of the new O-rings used?, four larger seal rings for the taller S type cooler?
