Hi, I was in the car breakers earlier today, looking for a 2 speed fan and switch, from a later R4. I found one in good condition, and, had to remove a radio console (as the one pictured above), to get the fan motor out.
I paid the princely sum of 10 euros for the lot.
So, there are some good R4 parts out there! one just has to keep looking around the breakers yards.
