They probably are still original equipment.

I found a place in the USA selling Leone KYB front struts for $53.70 USD each, free shipping within the USA
but I will have to inquire on shipping costs to Australia during US East Coast business hours.
I also forgot to ask about the cost of rear struts.
Would 1993 Leone struts fit a 1993 L Series?

My front passenger tyre had pretty severe tread wear on the outer edge,
and my passenger rear tyre, the bottom stick out more than the top,
so I think I should do a wheel alignment before I buy new tyres.
My last wheel alignment was around 230,000km's and it's now reading 311,000+kms.
