Gurus - in my swap from a 901 to 915 transmission, I see I need a new clutch pedal shaft (the bell crank bit) to match the travel of the clutch. With my 1969 pedal assembly, can anyone offer insights as to which bell crank (pedal shaft) I need? Pelican list the replacement for the later cars, but I don't know what changed in them over the years?

The part is now listed as: 930-423-027-01 For 1977-1986, but what is different about earlier cars? Am I better off to just look for an entire later pedal cluster?
