D2 Oil Drain Plug Gasket

My D2 (4U1826) is leaking oil at the drain plug of the diesel engine, but I'm unable to find a part number for the gasket in the parts book.  Does anyone have a part number?  I see the plug in the bellhousing shows 2, but not sure if it is the same plug as the engine base use.  Could someone confirm?  Red arrow on the graphic.  Thanks.

I would say the part number is 0L-1124 as you suspected. As far as I know all drain plugs are the same except the ones on the steering clutches.

The plug is l-827 and gasket l -1124 same from cluh housing

0L-1124, put separated side towards plug.

If it's just the drain plug all you need is a new copper washer that fits the drain plug.

Same as the bellhousing uses.

Thanks All. That's what I suspected but thought I'd check here before I ordered.
