Austrains....80'Class

Any Australians out there know the correct way to muont KDs to an Austrains 80’Class loco?
I have the converter kit. but i don’t want to “F” It up cause i cut something off i didn’t need to…
Any help / Picks of what it should look like would be Great!!!

Thanks Matt…

I used a #47 in the original mounting box, seems to work OK. Bit of Teflon dry lube helps too.
