Early Abody 4 Speeds!!

Was wondering what Ram Clutch set are you using in your car. It's hard finding numbers for early Darts with the 9.5 or 10.0 clutches. I contacted Clutch Master up in Detroit and they said that I should use a steel back carbon kevlar clutch since I'm running a 380+HP -- 360 Mopar crate engine and a small clutch. What are your thoughts?
