part number search: rubber plug for flexplate bolt access hole

[tcell70]

I'm doing a transmission replacement on my vehicle, and noticed that a plug or cover is missing from the flexplate bolt access hole that is built into the oil pan. To be clear, I'm not referring to the rubber plug that fills a slot shape on the bottom of the bell housing, not referring to the oil pan drain plug, not referring to the round access hole for the torque converter in the bell housing. There is a round hole in the oil pan itself that provides access to the flexplate-to-torque converter bolts. Apparently it should have a plug, but mine doesn't.

I'm not able to search for it effectively, as way too many things match when searching for trailblazer "oil pan" + plug, or transmission + plug, etc. Does anyone know or have an effective alternate for this part?

I found this one: http://oemcats.com/oem-parts/12565092.html. It's cleverly named "Oil Pan Hole Plug", and there are no dimensions.

But... looking at the diagram here: https://www.wholesalegmpartsonline.com/showAssembly.aspx?ukey_assembly=436385&ukey_product=2666561, it's item #31 and is the correct part.

so final answer: the correct GM part number for the "flexplate bolt access hole" in the oil pan is "12565092".
