I have a 1989 Syncro and need to know what type of outer front cv is required, no one in PE can help me

Question

I have taken the bus to various places and they can't tell me the type of cv, some people say that the Audi outer cv will work, can anyone help with the type or a part number.

My contact details are 078 203 5133 or email trsteelfabrication@hotmail.com
