Sorry, no pics; that was recollection from when I pulled them out years ago. They are definitely not easy to get to. Of the 4 on my twin engine 496HOs, I could only get to 3 of them. The center stringer was in the way of one of the inboard plugs.

Thanks. Are the plugs on an extrusion from the block or are they flush with the face of the block?
