I have a 1963 MM GT. I think it is a model 100. I am having problems with the clutch linkage. There is a tab "thing" on the clutch shaft that rides near the drive pulley on the trans. It appears as if it is supposed to engage the pulley at some point, but it has come loose, and the clutch is not working properly. If someone can post a link to a manual for this thing or post a picture of where it is supposed to be and how it is supposed to work that would be great.
