B230ET in OZ was centre thrust and weak skinny rods from factory - maybe engine was upgraded, if found in a 760T?
OZ market didn't get 760T after 1987 IIRC. K block (B230 with rear thrust & 63mm bearings) were introduced in YM1988, and 13mm rods appeared in K blocks from about early calendar year 1988.
That seller has lots of interesting stuff though.
