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.
