I screwed mine up... So my "help" will be what not to do. I didn't notice the difference in the forks until AFTER I had everything buttoned up. Then I got to the clutch slave installation and saw the later fork had no hole for the rod to pass through. After scratching my head for a few momments=, I called my buddy Les at CDM. "Hey Les", "Got this problem.", "Just installed an 80 5 speed and I can't hook up the clutch.". "No prob" he said, "Use the 4 speed fork!". Well, I couldn't follow his advice, because I had wore out my welcome to the auto shop's lift. They had PAYING customers waiting! So, I cut the rod to match the fork. That was more than a year ago, and it works fine, BUT, come the day my clutch needs adjusting, I'll be out of luck and will have to pull it all and do it right then. That's my "help".
