I am working on my son's 70 300c convertible,

I have a set of rear cables but the forward cable from the pedal to the adjustment bracket that attaches to the rear cables is frayed and will be short lived.

I can get a brand new cable from the pedal to the adjuster for a 71 but the OEM had different part numbers between 70 and 71.

The design looks the same for 70 and 71, in was in 72 that it changed a lot. the 70/71 wheelbase and just about everything else is the same.

Can I use the 71 cable on a 70?

Anybody know the differences?

Thanks
