I can see where the stampings on his March YH wheels jump all over the place and most of the ones you picture seem to line up with the K 1 9 at least. Some have dashes others don't. Do you think there was a strike or something in March that resulted in no wheels being produced? I know that the Mar-Apr time frame was big for Z28 production so I would think they might have run out if they were relying on stored up reserves from Dec-Feb. Interesting.

I agree with Jeff... if you look at the K19 stamping on your wheels, and look at the date stamps, they appear to be in-line or at least parallel to the K-19 stamp, on all the wheels you posted pics of, on the ebay ones, it appears every stamp was done randomly and no 2 numerals seem directly in line with the next... There ARE definite variations to the stampings on your wheels too though, including the dashes between the K 19 on some and not on others, the depth of the stamps, etc... so I wouldn't necesarrily say the ebay ones are suspicious based solely on the stampings, but if you have any info saying there were no YHs made during this time frame, that may make me wonder... did you e mail the seller and ask any questions?

There certainly are variations in stampings on the production YH wheels but there are also a few consistant characteristics. The K-1-9 appears to be stamped in a gang holder, the edge can be seen on the 8 6 stamping. The dates and application (YH) seem to have been stamped as individual characters with varying depths. The only wheels without the dash between the K-1-9 I have seen are the august '69 dated wheels. Who knows why they used a different gang holder set? Later '69 dated wheels also exhibit the dashes between characters. Other than the fact that the E-Bay wheels don't exhibit the gang holder stamp characteristics, have different fonts on the Y and H characters than other original YH wheels, no dashes between K-1-9 characters, and have (rare?) March '69 dates; they seem quite like regular production YH wheels! A lot of money for some "unique" YH wheels!

Here is what the stamping looks like on my spare. Barely readable. I see a K then a 1 to the right of the black smudge. A faint 2 next to the stem then YH.

I also have to agree that the stampings on the ebay wheels
look different than the 60 some that i have. I have never
seen a MARCH wheel, but most importantly the alignment does
not look right.....the K19 should be aligned and then dates should be aligned, usually left to right is the variance related to the valve stem hole. A picture on the
rim inside and near the lug hole would help to see if its
properly coded JJ wheel and K19 near the lug hole would
tell you if it is at least the correct rim and yr.
