first photo is 04B Norwood build

So is mine, late December '66.

My 06A 67 only has a P stamping on the lower portion underneath the lower door hinge next to the tulip

more PTB stamps
 

I finally got all of the dirt off of the tulip panels. More PTB stamps showed up!

Also - question - the trim tag has white paint under the black. What was the factory firewall paint sequence in 67? Should factory black be over the white on the tag?

I did a 67 that all three were under the heater cover on the firewall. Never in sight

This image may be helpful. This is a close up of a Norwood 1967 Camaro on the build truck coming over to body drop. This photo is also featured in the book.

A couple original 67 Camaros

Thanks Mike - obviously, someone has painted over mine. Also, the original firewall paint (behind the heater box - original heater core still in place) looks to be about 60% gloss. A lot more gloss than I would have expected.

Yes, very much on the gloss side. I have noticed the same under the heater box cover. You can't always go by what is in a book :D

This!!!
