The Autolite plug is also shown as a plug application for the late model Hemi engine.
It may not require adding the washers as you want to.

Art,
It double checked and the above plug is incorrect.
The confusion stems from your statement for a plug for a 2000 PT Cruiser cylinder head. The PT Cruiser was launched in 2000 as a 2001 model.
So, for a 2000 Neon application, the spark plug is not tapered, it uses a gasket and the above racing plug will work.
You should look at the tapered plug that Rich (quickford1) has available.
