Strut Tower Bar

I'm looking for a strut tower bar for my car. It's a 2001 chevy malibu with the 3.1 liter 3100 SFI motor. I've seen strut tower tie bars for malibus with the 2.4 liter 4 cyclinder motor but i don't know if that will also fit the 6 cyclinder engine, or if it doesn't where i can find one that will. help me out
