Got a classic Mustang that's not turning over? This Standard SS581T starter solenoid is the exact replacement for 1964-1973 Ford Mustangs. It's a brand new, direct-fit part that replaces the original solenoid on the fender wall. Made by Standard (SMP), with a manufacturer warranty included. Cross-references to Dorman, Delco, and others. If your starter clicks but doesn't engage, or you're dealing with intermittent starting issues, a fresh solenoid often solves the problem. Easy to install with basic tools—just disconnect the battery first! Keep your vintage Mustang starting reliably. Whether you're restoring, daily driving, or showing, this is a must-have spare part.
