Oil pump removal

[oriondal]

I’ve been going over some things on a 31 roadster I just got. I dropped the oil pan to check for sludge - not too bad, a little on the bottom. It’s been a few years since I removed the pan on an A, but I remember the oil pump coming out with the pan. This one’s bolted on the side of the engine, I’m pretty sure this is incorrect. Should I reinstall the pan, remove the bolt and put in a plug? What are the ramifications of leaving it like this?
