Sold original assembly line AC ACNITER 4 thin green stripe spark plugs R43 45S used

[AnthonyS]

Hi Gang, these have been in these boxes on a shelf for more than 45 years I'm told.

They are early factory assembly line installed take out plugs I was told - the original owner had, I'm also told, two LT-1 cars, one a 70 Z/28 Camaro and a 70 Corvette and was meticulous about their maintenance, such that he'd replace wearable items, but also keep them, "just in case". Anyway, here these are and some of the boxes are even numbered with which cylinder they were from.

Interestly, there's one 45S in two boxes and two of them in the third box for a total of four 45S plugs.

So, two and half sets of used R43 plugs 5569992 (20 pieces)

And one half set of used 45S plugs 5612171 (4 pieces)

I have heard that you can clean sparkplugs, so maybe that's what they were saved for, anyway, HARD to find original four thin green line plugs available here. And likely useable? Or at least for display maybe...

See detailed photos for conditions below - includes the boxes too, of course.

$240 PPG shipped to the US = that's only $10 per plug! Selling as a lot.

Cheers all,
Anthony
