Alright, I let my NGK bias show and ordered the NGK Rutheniums.
Also added to the order were COP boots(compromised on just changing those rather than the whole COP assembly) and a new intake plenum gasket.
Not sure if the last is needed, but it wasn't expensive for a Fel-Pro gasket(and that's a brand I respect/trust tremendously also) and I like to have a replacement gasket for any that I remove especially considering the age/mileage on this one.
Also happy that I've found a hood in-color to replace the one that got smashed by a tire tread at 70mph a few years ago and I've never gotten around to fixing. Hopefully I'll actually give this old car a new lease on life! If I'm going to get it running in tip top shape, I might as well have it looking that way too. I'd ideally like to find a new grille/bumper cover to go with this also(to replace the one that also got dinged, but not as badly) but I can make do for now.
