That depends on your model year. For the '65-'66, no. You'll need to get one of the bell-crank boosters, like the Scott Drake one available at Mustang Depot (Las Vegas). This is because the hole for the clutch rod (where the clutch MC will go) is too close to the hole for the brake rod. The '69-'70 has lots of room, so you'll be OK with the SSBC. The '67'-'68, I don't know.
