I can't give you drawings or pictures, but I can suggest another course of action. Get 1/8" brass plate (or thicker) that's about 3" square. Drill in appropriate mounting holes to match up to the 4 main holes in a 6800 card, drill two main holes over the inlet/outlet areas, then solder in two 1/2" ID copper 90 degree elbows. You now have a 6800 gpu block that flows even better now.
