Heavy Duty Clutch Pedal Assembly Value

Just my two cents. Mine= '68 cuda BB restoration. My understanding is that there is maybe three different swing pedal assemblies for this car. They range from light duty to heavy duty. On a BB car, the swing pedals have needle bearings instead of bushings and an over-center spring support bracket as seen in one of your photos. I don't know if these pedals were used on 340 cars. While the heavy duty pedals are somewhat scarce, most guys don't care as they are going to use a centerforce clutch and will be eliminating the overcenter spring. The only ones that would be interested in the heavy duty pedals would be those that are doing a very correct restoration. On the other hand, those guys are out there. My car has the original pedals, Borg & Beck clutch and it has points.
