Hi Bill,
The link you referenced is a picture of the vacuum line attachment to the brake vacuum booster. The "silver screw" in the picture is a hose clamp. You're a long ways from the clutch slave cylinder.
The bleed screw for the clutch is on the clutch slave cylinder. The slave cylinder is attached to the driver's side of the bellhousing, on the rear of the engine.
Dynamic should have given you a CD titled Superformance Mark III Installation Guide with your car. On page 12 there is a picture of the clutch slave cylinder.
Here's a copy of the picture on the CD.The bleed screw is on the left, sticking out of the top of the cylinder, behind the clutch hose connection.
