I don't either, unless you were starting a cowl tag collection. To be any use on a car, it would have to be an Ermine White 62 Chevy II convert with red and ivory interior and missing the cowl tag. Because they don't reproduce these interiors, you see very few 62 verts around with original trim. Most restore using 63 trim packages. Pretty difficult to match up this tag with a car.I don't know why anyone would want it.
It is probably legal to do this, depending on where you live to some extent.
A person can sell cowl tags on the net ... and one can probably even place a different cowl tag on a car legally.
A person can sell VIN plates on the net ... but it becomes illegal when one tries to put it on a car.
Just my opinions.
