Yep. I have not messed with motors earlier then 54 but I am assuming the rear freeze plug is in about the same place at the top part of the rear of the block. The bell housing completely covers this plug so the bell has to come off to get to the plug to replace it.

The plug lower right is the rear cam plug.
