Not a firewall marking, but here's the U80 option code written on the back of my rear speaker:

Here is my 64 impala

Built April 30


Firewall says  175-10-30    also model # 1847 same as yours

SO THE 30 MUST BE the Day produced

Also visible is the "PR" written sideways

I have also seen PR,   RP,  PRB,   not sure what they are.

 Does the 307-1-8    match up to anything on the cars cowl tag, or build date?

I am trying to figure out if there is a connection to what those numbers mean

Here is my firewall the way it looked before cleaning (I have owned the car since 1985). Note the C2.

Here is the untouched Trim Tag on my Oshawa 1967 Chevelle. Mine also has C2 in from the Trim Tag, just like the first picture of the Granada Gold 67 at the start of this thread.

Mine also say 2-12-13 like the Gold one, so the bodies came from Fisher Body the same day. My car was completed and shipped December 15th, 1966.

Found this picture on Kijiji of a 66 Olds Cutlass firewall.  Notice the "RX" above the heater box that we usually see on Acadians near the heater hoses.

we did some firewall detailing on clints 69 beaumont this weekend and we found a 51 on the firewall under the driver s fender his car is code 51 liberty blue



I found the paint code 52 (Matador Red) on my 69 when I was cleaning up the firewall as well. Mine was beside the wiper motor towards the left side of the car.  This marking was not visible until the black paint was removed from the firewall. The markings are on the primer, not the black paint that is applied later to cover up the overspray from the body colour. 
 I also found another marking to beside the heater blower motor opening that was covered by the outer heater box.
 I didn't put them back on because they were not visible when the car was built. I took pictures for later reference.

I heard of people taking pictures of these before a paint job. Then they duplicate them afterwards so it looks like there were always there.

I've seen these markings on various cars. I was wondering what the actual "value" of these markings might be? (not a smart alec remark). 
I was told that they are of significance with "totally unrestored" vehicles..,,original paint,..  etc.  Do the numbers have any other significance or value? 

Why would someone hesitate to paint over them on a vehicle that is being restored.?

Gotta love the messy way they painted those cowl tags! Seems like no 2 are the same.

As tacky as that data plate looks, It is factory correct. Red oxide was the primer color back in the day,hardly ever used anymore.{notorious for bleeding and hard to cover}

Yes, I've noticed that on a number of other cars too.

Certainly detailing was not foremost on the assembly lines.

A small firewall detail perhaps worth mentioning.

On a few 67 Oshawa cars anyway,
I've seen what appears to be brown primer sprayed somewhat crudely across the build plate without any tape masking.
The body colour comes on top of the primer and the plate appears to have been masked slightly better at this point.
The DumDum must have been added at final assembly.
It appears these plates were riveted on at the early body build and paint stage.
And some type of crude mask was attached at two different stages.
At first glance you'd think you were actually looking at a aftermarket underhood paintjob.

Showing off those original date coded plug wires, huh Mark???!!!




          Well, sort of, lol...but don't look to close at the coil wire, when I first got the car, in haste when doing a quick tuneup I replaced it...and pitched the original before I knew what I was looking at. What a bonehead! A lesson to be learned when you get a unmolested car I guess.
