20XE bearing sizes

[Iain]

Noticed somewhere selling two different widths of big end bearings for (C)20XEs, can anyone confirm if there are different fitments for different years? Widths are 19.3mm and 20.3mm. Measured my original big end bearings and I got 20.1mm?! lol

They're Glyco ones if it matters.

my catalogue shows both sizes, but not why there is a difference...

19.3 is also the old 8v 1800 (mk1 astra) size, and 20.3 is the later ecotec one. there must be a cutoff point, but i don't know when
