While cataloging another Butternut Yellow car (I have no life), I came across a 67 tag with what looks like a special paint code for the top. I thought the Z designator for special paint began in the 68 model year. Or am I reading it wrong? Or maybe the tag is a fake? The VIN for the car is 124377L109849.

Dido on no life either...Butternut & British Green (cool combo). Not sure about the fake part.

It would be a cool combo, but I don't think British Green was available until 68.
OOOPPPPPSSSS! Got me there...does look like SP. Maybe the owner opted for a White Stripe or no stripe at all.
Probably Y-2. Not a very good picture of the tag, but it looks like a reproduction to me. I'm no expert, so I could be wrong. I'll bow to Kurt and Daniel.
It's been on ebay three times within the last few months with no bids. HERE'S (http://cgi.ebay.com/ebaymotors/Chevrolet-Camaro-1967-Chevrolet-Camaro-RS-SS-_W0QQcmdZViewItemQQhashZitem4aad920d2fQQitemZ320739609903QQptZUSQ5fCarsQ5fTrucks) the last auction.

Really hard to tell from that pic - but I think it's Y-2 (same type of distortion problem as that recent Z22 tag pic) and I don't see any obvious signs that it's a repro tag.
If you zoom in on the tag it appears to be an upside down 2 (compare this to the other two 2's & the other Z).
