You should look at Tipo, Tempra, Fiat Coupe, Dedra, Alfa 145 - 146 - 155 for the axle beam. The part number you have given for the trailing arm is actually the whole sub assembly not just the arm. Yoou need to be careful with the arm because they changed the camber at some point. You don't want to end up with a replacement with a different camber to the other side.
