Review on High-performance Starter Solenoid - Victory Lap 66-132 by Raymond Gray

Don't listen to reviews about special connectors or the like. Get a 1/4" 4mm 12 point head and it will do the job just fine. fits like a glove and now my 20 year old starter turns like new and always starts. Don't waste your money on a new starter , as GM designed a damn good starter for these engines.The solenoid is both the contractor and the actuator.The contacts inside oxidize and also "weld" every time you start the car, eventually resulting in a bad one Connection leads If your starter sounds slow and you know you have good batteries, turn it on and save the old starter.
