There should be two bushings on the clutch fork rod end, one is steel with a slot to fit over the clutch rod for alignment and a tapered lock nut for adjusting the clutch fork between it and the Z bar end of the cross shaft and the other is hard plastic bushing with a flat surface on the Z bar end and tapered to fit into the clutch fork and the steel washer bushing
IHTHs I use the Mopar A body kit due to it having the longest clutch rod I'm not sure if they still sell it, I hope they do
If your talking about the shaft from the clutch pedal to the Z bar you need to keep in mind who assembled the cars back when
