Tyres (oh, title not long enough...)

Hi all

The old problem is cropping up. Time to get new tyres. I want to keep the XJ40 original so am looking for 220/R65 390 Avon CR39 (97V) Turbospeed. Yes, I know most people have bought new standard wheels so that they can fit alternative (and more available) tyres, but I want to keep the car as original as possible.

In Aust, but will import if essential (I usually end up doing that, but this is a try).

Can anyone help with sourcing?
