Here's a crazy idea that might work, if not mistaken the clutch disc plate from a Toyota Landcruiser is 10 1/2 or 10 3/4 inches and has the same spline number - but - the splines are just a slight bit angled, you'd have to see if it would run on your transmission shaft. Don't know if it will work for you, I run a chevy pressure plate and a toyota disc into my toyota transmission. Only problem i've had is the hyd. clutch just barely moves enough fluid to disengage the clutch.
