Something to think about.

The lower half of the flywheel cover. Does it have a small hole in it?

The 56's had a window and a cover plate. It makes draining the torque converter easier. Maybe worthwhile change.

The bottom cover on my 55 Patrician, was drilled out (I assume) enough to let you get a socket in there to drain the converter. I did not know it until I saw other 55's.
