9” 727 Torque Converter, 069J with ‘67 and Later Splines

The original 069J converters were built by B and M the later versions 509J were built by turbo action. They were not recommended for transbake cars as they did not have front and rear balloon plates and upgraded stators. I think you could get a transbrake 9" converter from Coan, Turbo Action etc. I think quite a few manufactures still offer a 9" converter.
