I seem to recall the Kaiser Wrecker has 18mm plugs. Correct?
I use NGK plugs because I think they do the job well. There's 3 plugs that cover most MV's.
B6S - 14mm thread, 3/8" reach fit Chev CMP, Jeep, Dodge VC/WC, some Harley, Aust Army ACCO. (= AC 44)
B6L - 14mm thread, 7/16" reach fit Ford CMP, Bren/Universal Carriers. (= Champion H10C)
AB-6 - 18mm thread, 1/2" reach fit pre '38 Ford V8 (some Marm-Herr, Eng Carriers), M37, M542, some Harley.
The NGK AB-6 cross-references to Autolite 3116, Champion D14, or AC R46.
