X Codes
« on: January 22, 2018, 11:48:48 PM »
I see a lot of people referring to the 69 Camaros using the "X Code" I.E. X11, X33, X77. I know that the X Codes didn't start showing up on the Norwood trim tags until the first or second week of Dec. 68. My question is would a car that was built before that or even the LA built cars that didn't have X Codes still be called ( Let say an LA built 69 Z/28 an X33) ?  Or does it have to have that code on the trim tag for that?

I am not sure about the LA cars but the Norwood plant did. I have an early 10D 69 Z/28 and during inspection JM found a X7 crayon marking on the bulk head behind the rear seat. I assume that is what they used going down the line to let them know how and what to assemble.

My SS is either an X22, or an X66, but I can't pinpoint which without original paperwork. 12A car, original engine, but no other indicators as to Style Trim or Plain Jane. Know it's not an RS, but stops there. Wish I knew for certain -

If the car is a coupe and has drip rail trim it was likely built with style trim.

I can offer the following related to your question based on my car;
LOS Van-Nuys Indy pace car (Obviously NO Z11 on the trim tag)
Fuel Tank sheet certianly had Z11AA typed in the lower section.

I still refer to it as a Z11 Pace Car, wether it was NOR OR LOS, it still is equipped with the package and content.

Best I remember, the back bulkhead is wiped clean. I'm considering taking a blacklight to it -

Shame, because the X7 my 01C X77 is as plain as the nose on my face. Never looked at the Pacer -

Thanks, Bill - I'll be sure to look at it if I ever get to the need of taking the back seat out of it.

Think I've settled the question on the SS - it's not a style trim, so I'll going back to the X66 car that I've thought it was all along. Too many things absent to believe it was Style Trim.

You don't say if it has/had wheel lip chrome. If it doesn't have it there will be no holes to attach them in the rear. Also there would be no holes in the front fender extensions. You would need to drill them. I just found this out so I have to go back & weld up all the holes that I put in it in 1981. Mine is an X66......Joe

Norwood was still using the crayon on the bulk head even after the X codes appeared on the trim tag, at least early on I'm certain.   My 12D 69 RS Z is of course an X33 on the tag, and also has "X3" written on the bulkhead.

Although this is still only about 2 weeks into the X codes on the trim tags, I'm curious did Norwood continue writing on the bulk heads throughout production??   Would there be a need to have it in both locations during production?

I was under the impression that it was needed for the assembly line for operations occurring before the trim tag was even installed.

Where is the bulk head you are referring to.  Is it behind the rear seat or under the dash on the firewall?

Jim, I'm assuming the Van Nuys plant did not write codes on the bulkheads?

I think I understand what you are trying to convey with your question.  My feeling is that the X code slang thrown around originates with the Norwood cars and their trim tags.  So when I hear the term, I automatically picture in my mind that it's at least a Norwood built car from 12B 68 and beyond.     Anything else and we are talking about Pre 12B Norwood, or a Van Nuys production run Camaro.

But it can all be interpreted any way you see fit.  No right or wrong.  I suppose a Van Nuys Camaro can be referred to as the same thing if there is some sort of paperwork to confirm it, but in my mind it's still more of a trim tag thing and only 12B and beyond Norwood cars fit that idea that the description was intended for.

The X crayon mark is usually found behind the pass side of back seat, near where the vinyl overhang of the package tray is glued.

Fisher did not always put partial X codes there. I have seen interior paint codes such as DK GRN or BLU in the same area.

Did the LA plant use the X Code terminology like the Norwood plant? Was the X Code found on any paper work? (LA or Norwood)

The body tag was of no use to Chevrolet Assembly; they did not reference it. Body and Chassis Broadcast Copies were generated by Chevrolet when the completed body was released to final assembly. X codes were not relevant to Chevrolet; never seen them on any paperwork. 

X codes refer to specific body build configurations. It is likely that both Fisher Body plants used the same engineering information to build Camaro bodies. For some reason, Fisher made the decision to add the info to Camaro body tags late Dec 1968 but only at Norwood.

There had to be other means of conveying Fisher Body build information at both plants. Certain options required slight differences in body fab; RS, dual exhaust, spoilers, etc. Carefully media blasting a body often reveals option codes written on the firewall in grease pencil: M20, N10, Z22, etc. Maybe that's all they did.

BTW the firewall graffiti prominently seen on some restorations is inaccurate. The writing was done on the uncoated body and all of it was covered during firewall blackout. Over time, the paint can flake off the crayon and some of it becomes visible. On occasion, I have seen the assembly sequence number written on a body after paint. Workers were supposed to remove it.
