I've just found that 'run-on' models are permitted to take part in this rally from St Kilda to the Cape Schanck resort on 25th October. As the Series 2 came out in '58 all Series 2's (not 2a's) would be eligible, mind you they aren't likely to be LR experts so any Series 2 would probably get in.

Details are in the thread below along with a link to the RACV where you can download an entry form.
