Plug cross-ref

#1

Looking for the old J12YC Champion or equivalent. Local auto parts counter jockeys no help. Anybody have numbers for other brands equivalent of this plug? This is for my truck, a 1973 International Harvester. Radio doesn't work, don't need resistor plugs and I can make it start and idle a lot better with non-resistor plugs and copper cables.
Also looking for various manuf's numbers for a long-reach non-resistor plug with 5/8" hex. Like Champion N11YC but with the smaller hex. This is for the plugs on the right side of my bike's STD heads.
Not much luck searching the web for usable plug info and cross-referencing though I'll keep trying.

Good links Jack!! I like NGK, good plugs!!

Kell, if you strike out on the 5/8 hex with a long reach, HD uses a 6R12 in the new Twin-cams & sporty's..
both have 5/8 hex & long reach. Only bummer is the R=resistor.. Oh well.
