No, the pressure fit metal cup on the DA an many others are
the negative side of the ignition. The feed wire is in the center
of the cup/wire and it is shielded.
My question still stands... Besides the possibility of a loose connection
with a bolt, why would the manufactures rely on a pressure fit for the
ground/negative side of the plug?
For that matter why rely on a spring tension on the positive side when
the plug could have a bolt or nut to attach the positive wire?

"As it stands now we only have a pressure fit around the spark plug
for the negative side of the ignition"
NO thats the +ve side
the engine is the earth side so you cant use it as the +ve feed
