i got a set of shocks for my 69 404 sedan ,a year or so ago from EAI ,dont forget to loob the bearings that the struts rotate on ,that made a big difference on the steering on mine
If you don't have any luck in Oz this guy is worth trying. He is in Athens and has a large stock of NOS Peugeot and Renault bits
I got NOS Peugeot 404 front struts from him with no fuss, no delay and at a fair price. Found him good to deal with and he pops up on almost all old Peugeot eBay searches
