I had a Milodon one and it rubbed when the Milodon deep sump pan was installed. I was turning the engine over by hand and heard a super faint metal on metal sound so I took the pan off and the sound went away. I had already trimmed material off the sides of it and it still rubbed despite it having what appeared to be plenty of clearance with the pan off.

I would put some clay on whatever one your using and then turn it by hand with the pan on and then pull the pan back off to check for any contact. The Milodon one was too wide for the pan and would get wedged up and distorted enough that it would touch the longer crank throws,
