58-74 All Except 58-61 2 X 4. This is the only rotor on the market that has the correct extended copper tip that closes the gap left by other rotors between the rotor tip and the distributor cap terminals. All rotors since the 70s have a 1/8" gap between the rotor tip and the distributor cap terminals. In the 60s this was the rotor that was used by all the Hi Performance GM Engines! No matter what ignition system you have, you need this rotor. This new rotor closes the gap on: * Poor Starting - A Closer Gap = Easier Start * Eliminates Crossfires, HI RPM Missfires, Fouled Plugs & Other Weak Spark Symptoms * Your Ignition Coil Will Last Longer, Because It Doesnt Have To Work As Hard To Bridge The Gap * Pure Copper = Better Conductivity = Better Performance * Close Manufacturing Tolerances, Means a Perfect Fit * Comes With Original Screws Electrical components such as distributor rotors are non-returnable parts. Always refer to a factory service manual when diagnosing engine service problems. You can damage electrical components if the proper procedures are not followed. Be sure you are replacing the correct part. Size: N/A
