a833 with 904 yoke??

The A-833 isn't the only 4 speed that came in Chrysler products through the years. Are you sure that's what you have? Borg Warner and Saginaw were in the fray as well, although rarely ever mentioned because they were not performance oriented transmissions. A lot of people aren't even aware of it, but it's true. I've seen quite a few. Trucks, and F bodies were the primary users I believe, but I think they also came in others as well. The BW and Saginaw all came with the small yoke output shaft. Are you sure what you have is an A-833?
