I've listed the bits you read wrong:

it'll be 7/75 BHJ28991A
GVW 2155kg

BODY 158402

The rest looks OK. It was originally a low compression 173 (2.85L) with 3spd column shift and 3.55:1 diff. Probably 4 wheel drums too.

Paint colour 0904 is Kiewa Grey, a fleet colour used by SEC Victoria, so probably what yours was originally ie an SEC vehicle. I recorded a few cars in this colour in an old wrecking yard north of Ballarat earlier this year. Here is the colour:

The trim (64V) is called Fawn on a HJ Holden. Yours is pretty much close to the last of the bench seat 64V cars for HJ. From 8/75 onwards the bench seat Fawn became 64W, only bucket seat and Kingswood got 64V after that.
