<br /><br />I know...darn things are expensive. Afore I got fancy and bought one, I took a square of plywood and mounted four long screws from each corner aiming at the center. I ground the screw ends to a point also. In the center of the plywood, I rigged a post for ground with a large alligator clip comin' out the back. I could then adjust the screws for different gaps. All I did was run the spark plug wires to the screw heads, clipped the clip to a good ground. Crude...but it worked.
