Vernatherm and oil screen gasket part numbers

[S. Soule]

I have a slow drip of oil from the bottom of the Vernatherm. Looks like I will need to remove the large nut, inspect and put on a new washer/gasket. What's the part number for that washer? While I'm posting, what's the part number for the gasket/washer for the oil screen? I should have a few of those on hand too.

Lycoming 76510 for the vernatherm. 300 in-lbs.

AN900-16, aka MS35769-21 for the sump screen. I think the book says 270 degrees after gasket contact, but most folks just crank until firm.
