Hi wce
Those blades pictured won't fit - they are for 1974 onwards utes. The ones gadge mentioned do not have the dome at the bolt, are marginally longer and have a slight fan at the back.
I wouldn't hesitate to put these on

It's not like you are probably ever going to expect it to slash down 1 metre high weeds ever again in its life, so these are fine for the occasional run over a lawn - might even help it mulch and throw better (more airflow due to bigger fan)
