    What markings would a 70 X auto non ac car have on the firewall?

    "D" behind the booster/master cylinder, paint code behind the voltage regulator.

    Is the consensus that the paint code was in fact on the black and not under the black, or is that still up in the air?? What about the cowl markings I've seen several cars with OK and random 3 digits on the "saddlebags" as some guys call them. Any "OK's" on the firewall??

    Here's a cowl pic of the X we restored showing "Q". But this car has AC. Hope this helps some.

    92C46320-B072-4489-8B94-0EECD9D95208.jpeg It was always over the black paint. Q Q on a yellow and 10 10 on white. Behind Booster 70 GSX is D in yellow crayon. If a 4 spd DC. There is much debate on crayon color for paint codes. Is it white or engine faded yellow. I have seen quite a few and I say white. My guess it was put on by different guy at different place because paint code would be put on after black paint but before body color so done by Fisher. Yellow D would be put on later because they did not want overspray to obscure it. All Flint built cars from GSX to lowly 4 door cars I have seen were done this way. Just my theories. I copied my GSX the best I could.

    The Green on the back of the Spindle means it was a disc brake spindle, drum brake spindles were a different color. I believe the Orange at the top meant heavy duty. I have only seen that on disc spindles.

    You will also often see "inspection marks" on various parts of the suspension/drivetrain. These are basically paint dabs the inspectors put on the parts to "document" they were either torqued or installed correctly.

    Now factories use colored paint pens for inspection marks. They are all over the place on my Challenger Hellcat. Less messy than a paint brush for sure.

    That’s cool. I have not seen those at all on cars Buick’s? The 50B car above didn’t have it? Burnished saddle notch back bench seat.

    Dave,
    Yeah different plants did different things, and some of it changed during the model years as well. My 69 Oshawa built car does not have any markings behind the power booster.

    All the Framingham cars in local yards have nothing too but Flint cars do.

    Should I put 10-10 or just 10 for the paint code, is "188" anywhere, seems like I've seen the interior code on the saddle bags before

    Is it a Flint Car? If so I would put 10 10 no dash if in fact upper and lower is white? No vinyl top right? I am not saying no cars had the interior code but I have never seen one except for car posted here. The numbers on the saddle bags I have not figured out? Production line number maybe?
