Put the snubber up against the floorboard an try again (if it's not already)..... If you still get a shudder, then I'd say for positive the clutch has to be the issue.
This made a difference. I wedged a couple 2x4's between the snubber and the floor board and the shudder is virtually gone. What does this mean if my pinion angle is at -2* relative to the engine centerline?
