Request: IO-540-D4A5 oil sump picture

Does anyone have a good picture that they could post of the inside of an IO-540-D4A5 oil sump that shows the oil pickup hole and the two boss holes that you would use to drain oil? I’m trying to determine how far apart these holes are from one another.

I found many good drawings from the Lycoming parts manual and from a web search, but all were at an angle that didn’t show the pickup or the boss holes very well.

Thanks,

Keith
