Those should be available at any local shop worth it's salt. They all have the same number of links but the rod length itself varies depending on if it has a coaster brake or not. Run you about $8.00.
I believe they make 3 different one's to date. They may have made others WAY back but the 3 most common are still being made.

I did not know that. My bike is a three speed non-coaster. I am sure my LBS can get these, but I wanted original parts for my white Corvette.
