There were two types of adjustable after thoughts to the clutch linkage. Early on there was an adjustable rod that replaced the piston rod going into the the master cyl. This was a bad idea and could cause problems if adjusted too long. There is an adjustable link that replaces a part of the linkage between the pedal and the master cyl piston rod that works great. I know Rob Grady sells this and possibly others do as well.
