Figure 1 Determining Rotor Screw Length.

1. Note which spark plug wire connects to which terminal to ensure correct routing when reassembling. Remove the existing distributor cap and rotor.

2. Before installing the Cap Spacer you need to determine which length rotor screw should be used. In some applications, the longer screw could make contact with the magnetic pickup and cause damage. Figure 1 shows the difference.

3. After selecting the correct rotor screws, ﬁt the Adapter to the distributor base (Figure 2). The snap tangs will secure to the base of the distributor just like the original cap.

Note: You can also use the supplied screws to hold the spacer

(Figure 3).

4. Install the new rotor. Note the position of the domed washers. The dome must face up.

5. Install the new distributor cap followed by the spark plug wires. Install the optional retainer with the supplied screws.
