I could use some help. When i'm Driving I can shift normally however every once in a while the clutch will fail to engage fully and the car will start to roll off in which ever gear you have it in first or reverse normally.

I have Checked Fluid for the clutch Fluid and its stays full. My best Guess is a Failing master Cylinder. I really Don't want to replace the old one with a new plastic master Cylinder but thats all i seem to be able to find so if anyone has a link to site with a full metal one I would be very Grateful. hopefully under $150

Also I'm Looking for a adjustable clutch rod as the dam pedal is way to high.
