1970 Challenger 6 Pack Carb Parts

Does anyone know someone that might have some old 6 pack carb parts? I need to original pivot bolt for the secondary carb linkage. It's looks like the updated version is a completely different style bolt. I need the original one with the cotter pin (see pic below) not the newer version with the nut on the end.

There has to be someone out there who might have some old parts laying around.

Any help greatly appreciated
