I decided to do some test stamps today. However before I started I decided to clean up the stamps to see if I could yield a better result.

Here is the stamp before I worked on it. You can see all of the excess rubber around the B.



First I drilled out the holes in the B with a 3/16 drill. Here you can see the holes drilled in the B & The P.



Next I trimmed the excess material around the cut out Letters with a razor blade.



Then I tried a few test stamps with some latex paint and a piece of plywood. Not an ideal situation, but enough to indicate if I am going in the right direction. As you can see I used a foam brush to apply the paint to the stamps. I found that the key is to apply the least amount of paint possible. Next time I will try an even smaller foam brush and thinner paint on a metal surface. That should give me a better idea of how close I can get to what I am looking for.



The test turned out ok overall. The second one from the bottom was the first test and the driest. I also pressed the lightest on that stamp. The harder you press the more distorted the stamp will be. The rubber stamp is fairly firm, but the black rubber underneath the clear rubber is very soft and compresses quite easily.

1969 Camaro SS 396

Just curious if the Blue D90 stripe was a factory special order stripe or added to match the 715 interior. Looks great IMO. Can't go wrong with the Cortez Combo!

Not exactly sure but the rear tail panel is also blue.  The sign in front of the car says that its has the "Nickey" package, so maybe this was done at the dealer before it was sold???

Didn't see the rear tail pan picture.

I am no expert, but all of the 7's posted in this thread so far look to be the same to me. With Consistent tail curve.

JohnZ over the years has mentioned many times here and on other forums print spec's gave the supplier either option but since the clear zinc was cheaper that is what suppliers mostly used. This was before what we know now about cad plating.

Hey Chick what do we know about cad plating now?
Health/Cancer issue!

Are you referring to the plating process itself? What is the difference in health risk between Cad and Zink? Sorry I am new to this. Perhaps I should google it. Both processes are still in use correct?
I ain't no doctor Mike LOL Smiley but yes both processes are still in use. Cad producing shops are mostly used by the aeronautical and military sectors. Due to health concerns with cancer I believe those shops are closely monitored (OSHA).  We did not have any cad in any mfg. plants I worked in so NO expert here......

Thanks Chick I will follow up on it. Always good to be well informed if there are any hazards in our hobby.

The 1968 Z/28 Engine Compartment picture came from the September/October 1996 Camaro Enthusiast.

Contents Page
for page 36
"ENGINE COMPARTMENT DETAILING '67 - '69
Many Camaro engine compartments are the same after '69 as far as what is
painted what.  Most '70 - '74 were identical with few exceptions.  However this
article is dedicated to the 1st Generation Owners.  The photo is a 1968 Z28
engine compartment from Chevrolet.  We reproduced the photo full size so you
may see the details, and then put the arrows with numbers on the same picture."

The article is pages 36-39.  The previous picture is page 36.  Here's pages 37 - 39.


Great article David. Thanks for posting.

Great shot of the factory PTB stamps. Although faint even when new, they do appear quite crisp and clear.
Why is the "P" a reverse stamp on the right side and upside down on the left side?  How did they do a reverse stamp? Upside down is very common. George

Good question.

His had BLACK and the PTB on the pass side but no sequence number on the firewall, it was  (80) on the top of the fuel tank and the top of the heater box.

Yes that was it. I thought it was a 50. All good info James.

Thanks again Jerry!  I found a link to a larger version of that picture on this site:






Anyone else notice the grease pencil mark on the firewall above the top heater hose? SO? SQ 5O?


Yes I noticed that as well. Didn't Lloyds car have the same marking?
