You won't find a twin-bore TB for a 5.0 anywhere because they don't exist. They only put twin bore units on certain 4.6 modular models including the Bullitt. You can get a 75mm single bore TB that'll provide more than enough airflow for your needs. Just port the opening of the intake manifold to the same diameter.
Don't expect a dramatic improvement in performance (your existing 65mm TB is pretty decent) but the throttle response does become sharper and that alone can make it worthwhile especially when combined with a CAI and MAF.
