I have what I'm told are Punto GT front calipers on my Seicento. They need a rebuild but it seems there are at least 2 different calipers for the PGT and I cant identify them. Ebay is no help as It's just throwing up contradictions. Basically they have a steel wire across the outside side of the caliper which inserts into the main body and grips the carrier. Most PGT calipers I have seen do not have this. Can anyone confirm with certainty which model/year of PGT these are from as I cant provide a number plate to suppliers. Many thanks.
