Converter- 67 273/904

Just wondering if I need to order anything "special" to replace the converter in my 67 Dart? I seem to recall something about input shaft differences in early transmissions.

I am getting ready to rebuild the 904, and figured I would switch to a slightly higher stall to help the little motor out.

I have a 4bbl to install on the motor, and have installed a 3.55 gear. So I figured a 2000ish converter would help wake up the motor a little more.
