Torque converter
You can send it to any of the well known converter suppliers and they can rebuild it the way you want. The converter is usually a custom type of purchase. You have to supply them with alot of specs though if you want it right (weight, gear ratio etc). Call one of them and they can talk you through what they need and then ship it. They can build it to work with your combo. Without them doing the work, I don't think they can tell you much. It usually takes a couple weeks for the rebuild and shipping.
