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

[bachmoza]

Four underside hole sizes of S oil cooler(996-107-025-59) look all same to me on photos searched at Pelican. But for those of non-S cooler(996-107-025-07), two inner holes are definitely larger than two outer ones, and the O-rings Nr 21 and 22 listed on Sunset and Atlanta are available in 3 different sizes; two 26x3, four 35x4 and two 18.77x1.78.

By JFP in PA ​s oil cooler on a non s?. S oil cooler(996-107-025-59) the latest version is switchable, I understood, to the base 2.5L Boxster, my 1999 Tiptronic, except only the very earliest 2.5L cars (1997 and early 1998) with intermediate piece.

Am I straying too far?
