The clutch pedal on my 64 1/2 3 speed recently began staying on the floor after releasing it during gear changes. In order to return the clutch pedal, I have been pulling it back up with my foot as I drive. This is not an ideal situation! Once I get the pedal about half way up with my foot, it will pop back up the rest of the way on it's own. I suspected the bushings and return spring on the clutch Z bar as there was quite a bit of slop in that to begin with. So, I replaced the bushings and return spring figuring that would solve the problem. Well, it did not solve the problem at all. I checked the clutch pedal support and I cannot detect any wear that would cause the problem there. Maybe I just couldn't get a good enough look at it. So, now I'm suspecting that it is the pressure plate, but I don't know. Does anyone have any suggestions as to what I should do next? Replace the clutch or focus on the pedal support?
