A Caliper Piston


Vehicle Information: Year: 1982; Body Type: Coupe;

I have a 1973 911 Targa, and I am updating to A calipers. I bought a set of used 1982 calipers, started to rebuild them, and find that the pistons have scratches on them. I want to replace these pistons. Will the replacement stainless steel pistons made for the Aluminum S calipers work, or do I need A pistons. If it is the A pistons, where can I buy these?John.
