Exactly! Yes, some plugs have a threaded post; get these and throw away the
round ignition wire nut and replace with a stainless nut of same thread.
Also include some stainless flat washers and star washers. Find ring lugs of
suitable size for your open feed wire, crimp AND solder), then torque down
"just so" onto the plug's "anode". Careful....the plugs will strip without
too many ft-lbs torque. Coat the whole connection with KOPR-SHIELD or other
anti-oxidant goo.
BTW the wire that grounds the metal block to your ground system should be
BIG...#4 or bigger, OR use a big fat piece of the copper strap your mention.
