today i have found these calipers. I don´t know if they´re the same. They are in a old Volvo, i think 140, but they´re 4 pistons.

This is the car.
I was close to buy them. they were asking just 120 € for both calipers, but i was not sure. It looks that something is different.
Also i have find these ones, but they were asking for 1000 €. they were in a Lancia Kappa. with a Alfa 3.0 24 v engine. I think every is the same as the 164. these,as minimum, must to be to fit ia a 16" or 17" rims.
