These were purchased from Ames Performance in NH 16 years ago. They are in their original GM boxes and there are no barcodes anywhere.
Easiest would be to ask Ames what they have sold 16 years ago. I´m sure they still know if they sold original GM parts and/or repros during this time... They normally sell parts out of their catalogs, no individual parts as Rick´s First Gen has done (now owned by Eckler´s, so these times are over, too...)
