However, in these pics, the arrows point to areas on both pieces that seems to show what looks like the appearance of something that was there.

That part diagram is unlike any Fordomatic layout I have ever seen.  It looks more like a Hydramatic layout.  If your Lincoln has a Hydro, then a gasket would be needed because the transmission side of the flywheel is exposed to the fluid and would leak out between the flywheel and crankshaft without a gasket.  I would think sealant would be required on the bolt threads also.

There is a gasket between the flywheel and tranny. And it is called hydramatic

Some Ford flexplates have a metal ring that fits there.  It gives more strength to the flexplate mounting area to prevent cracks.  The ring fits between the flexplate and the bolts sort of like washers under the bolt heads.  I am not familiar with the 317 personally.  Just have built dozens of Ford engines over the last 62 years or so.  Joe-JDC

Just talked to my rebuilder. He said there is nothing between the crank and flywheel. That answers that

If the diagram is correct for your application, it shows part 6377 between the converter and the crankshaft flange. It's identified as a gasket. Were there two different transmissions used in the 54 Capri? My knowledge of these cars is pretty much zip.

What the man said. It is needed. Study how the torus is assembled.

I thought I read where you found one. Can you give the source?

It was a 3" o ring. It was from Charlie's transmissions. The link is above. I asked him if a gasket is required and he stated that he's not a mechanic.
If a gasket is required, any idea what material it would be made of?
My mechanic said the same thing someone earlier said, that it would cause a wobble if or when it wore down. He was quite sure that one isn't needed. I don't see where fluid would be near that area to leak out.

This is the tranny. It's sealed.

Now ain't that some shiat.

Operate an AT PARTS HOUSE and has no idea what is needed for a particular transmission.

The gasket came in the 317 ENGINE OVERHAUL GASKET SET also.

The torus is basically just a convertor and there is fluid inside of it.
