Please help identify to the brembo brake pad

I bought used 4-piston calipers from Alfa Romeo.
The seller told's me about this calipers: They are from Alfa 159!
But the calipers is gray color and BREMBO word is on the face side.
On the rear side of caliper we have alfa romeo logo.

On Brake pads written this numbers:

FERODO 4446/1
BREMBO XA0.40.98
and Alfa Romeo Logo!

There is a caliper (the number on caliper is 20.7926.02):

I need to know original Fiat/Alfa/Lancia number...

Part my English, i am from Russia.

I'm pretty sure the Alfa Romeo part number is 77363545, and the Pagid number is T5113.

The dimensions are:
Width [mm] 131,6
Height [mm] 77,2
Thickness [mm] 16

I hope this helps!

I am sorry, but no Pads 77363545 are bigger and not the same shape

Okay, I've had a look at all the 159 options, and none seem to match. So I had a look at the 156 GTA brakes (which are also Brembo's), and these are smaller pads.

The dimensions are:
Width [mm] 109,8
Height [mm] 69,3
Thickness [mm] 18

Part number: 9947643 or 9950812 (new number 7736 2227).

Maybe worth a try?

The caliper is not from 159.
If there is an Alfa-Lancia-Fiat Logo on the rear side is more possible to be from Fiat grande punto Abarth.

They are not from an Alfa. but may fit an alfa. They look to me like the calipers from a Fiat Coupe Turbo.

Which are the same as the GTA & GTV3.0's... Hmmm....

But fit the 305mm discs (pre 2003 GTA). The GTA's are 330mm after that.
