putting one of these adapters in. So removed the center filter mount "bolt" and this tin plate fell off with a gasket behind it to the engine (call this gasket 1).
So I have a gasket kit which is a big flat gasket like the gasket on the engine which I call "new gasket". a thick cork o ring and thinner o ring. along with the long bolt and the 90 degree aluminum piece.

What is the proper order to put things back on?

Most importantly,
Do I need to reuse the flat tin plate (with its existing gasket)?

My first thought is,

1.leave orig gasket there,

2.pop the tin plate back on,
next is the new large flat gasket same size as one stuck to block

3. put alum adapter on

4. put the two smaller gaskets on bolt, then tighten up.

I'm thinking that may not be right and appreciate any comments please.
