How to know the type of motor of a peugeot 206

Hello, I need a spare for a Peugeot 206 Anio 2005, download the parts manual for this vehicle but there are 4 different models, although you already discard one for being 3 doors and another for being diesel fuel, but to differentiate the other 2, do I have to look for motor or chassis number? And also, the mechanic has told me that the replacement is called a retainer of the direction mace, but in the manual only something called a amount, arm and front mace, related to suspension. Is it the same? My problem is that I am not in my country that is where my car is, and we want to look for it in the United States. I will thank you very much if someone can clarify those doubts.

I do not think you get it in the US, I never saw that there was Peugeot 206, but put me the full chassis number and tell you what engine you have.
I put a front train diagram to tell me what you need, A or 2?
