Hi - searched for this, couldn't find specific help:

So, the old OB service manual says W145-T30 plugs. AFAIK this translates to a W8DC nowadays. Everyone here seems to cite W7DC as the "right" plug - is this true for ALL model years, or does a '79 USA 4.5 actually use a W8DC?

thanks!

edit: Bosch's parts website says WR8DS is the correct plug. That pops up all over this site in the search (W8DC does not). Consider this closed...
