I bought a project 71 dart that has a 904 behind a 360ci while I had it apart to rebuild the engine I tried to identify the converter it has the numbers 8419994 11741 904 mx 5202 painted black, tried looking up numbers online on every manufacturer I could think of and just Google but came up empty, engine and trans was put in the car in the early 90s. The guy didn't have much info on the car and wasn't very knowledgeable so I couldn't ask him. Maybe someone on here might remember the part numbers. thanks
