engine and trans pad stamps

[Stefano]

I would say the stamps on my former Corvette were the same characters.

On '67 Corvettes they didn't use the same holder. They forgot to advance the number when they hit the transmission on my '67. The build date of the transmission matches the Warranty Plate and engine and transmission have never been out of the car.

Sorry Stephano, I was working from this picture that you posted. For some reason that detail did not show up.
That other picture is better.

Love it.

Ten years ago I would have sworn up and down that we never let any of these out because we were so diligent to check and repair on the line.

Now - I've seen literally hundreds of assembly line mistakes relative to VINs (mostly trucks). I never would have believed it.

That's correct - <span style="font-weight: bold">Corvette</span> was different in the 60's, and the transmission partial VIN format changed several times.

In '63-'64, the engine and transmission used the same partial VIN format (model year followed by the last six of the VIN), so the same gang holder was used to smack both parts after the transmission was bolted to the bellhousing.

That format continued into the '65 model, but it changed early in November until the end of the model year, with an &quot;S&quot; (instead of a number for the model year) followed by the last six of the VIN. This required different gang holders for the engine and transmission, as the engine partial VIN format remained the same as '63-'64.

For 1966, the transmission stamp format changed <span style="font-weight: bold">AGAIN</span>, adding a &quot;6&quot; prior to the &quot;S123456&quot;. That format carried over into 1967, using a &quot;7&quot; instead of the &quot;6&quot;.

The <span style="font-weight: bold">engine</span> partial VIN format never changed from 1961-1967; it always had the model year as the first digit, followed by the last six of the VIN. The longer-format partial VIN (18Sxxxxxx) started in 1968.
