Use a '69 351w equalizer bar, with the original 68 upper linkage going to the clutch pedal and the 69 lower linkage going to the clutch fork. You can use the "standard" clutch release
fork, nothing particular there.....
65-70 "frame" rails are in the same place, but as I recall, the 351W block is wider?.....
hence the z-bar choice.
As the drill sergeant said, "I taught you everything you know. I didn't teach you everything I know."
"Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so."
