A7SS/A10 Primary Crankcase Spacer. 42-7518 .Gaskets or not?

[Peter Gee]

Do not appear to be any listed, but could be a huge source of leaks.

My approach would be, a great place ( one of the few) for a good silicone gasket compound on both sides of the spacer 42-7518, with the primary case joint face greased beofre offering up, progressive tightening over 12 hours to form a film..and removable primary afterwards, if ever needed????
