Recently I purchased a set of the AC43 reproduction spark plugs for $59.95 to compare to originals. I must say after installation one would have a difficult time knowing original or repro, as the differences are in the spring washer and script & knurl on the lower barrel of the spark plug. Script on the originals is "AC SPARK PLUG FLINT MICH MADE IN U.S.A." Repro plug on right side!

Look pretty good - I didn't realize somebody was reproducing them.
Besides the barrel knurling and washer, there's another hidden difference in the electrode tip (fluted). I'd be proud to use these - who's offering them ?

Steve

Steve, happened to see and purchase from Zip Corvette for $59.95. They also have R44 for same price!

Great information Chick. Thanks for posting it. I’ve recently looked at purchasing original AC 43’s and will use the info to either do so or to purchase the reproductions.
