I have chased up the possibility of the electric PS kit with EZ in Holland and got a quick reply this time from them on

They have done a 408 and I reclkon it's the same as a non PS 409 going by parts book
Cost is 2350 Euros and 175 Euros freight to Australia
They also told me of their agent in Australia, in Sydney, but I got no reply from last time.
Availability of this may well shed a whole new light on how long I keep the car, as a shoulder injury gives me a niggle these days!
