give patrick a call he will do any custom work you need im sure . i have seen in the past other TC members that have sent carbs to patrick i have one of his dominators and i have to say he knows his stuff . from this day forward i will buy all my carbs from him . try talking to mike lewis TC member wolfplace im sure he can help you get a deal from prosystems should you decide you want a new carb instead of fixing your old one.
