1964 904a transmission (push Button) torque converter.

Actually, 60-67 will work. If you don't find anything locally, I have a couple, but I'm in Florida
The LA motor was first produced in 1964 so what would fit on that from 1960? A converter from a slant? I am trying to learn about these things so I don't trash the input shaft on the transmission. I had a tranny shop already destroy the tranny when he put a later model planetary in the unit and then hooked up my original Torque converter, it sounded like a blender when the engine was started.
