LOL, no need to wrench or twist on this one at all. Every digit or letter appears as an inspectors stamp at 1969 Lynch Road except the following: 5,6,9,I,M,Q,V, and Y. I assure you there is no relation between them.

Big D what do you make of these? Tire info on the left so what's the need for SHX or SXX or SHY or.........???

The SHX marking is a single persons mark, initials, or ? We have also seen him/her mark in other areas. I have photos of the SHX behind the side scoops on a car. Pretty sure some where else. With that said, I am confident the SHX is a rogue employee with a grease stick. I am confident it has nothing to do do with the topic at hand with regard to tires.

I am assembling a post on the 70X marking we see so much of to answer your other questions but it is past my bed time so stay tuned tomorrow....

D

EDIT (5/7/22): Not a rogue employee for the "SHY" marking. The term "SHY" shows up on the final line inspection document. Meaning unknown at this point.

Doing a little housekeeping. Original Poster (ZIPPY), can you share your complete VIN/tag with me so I can get the data documented and logged. Do you have other documentation with the car, BS or WS. Please PM me here. Thank you.

We are down many paths with this thread, but all are tied together with the trunk graffiti. I have never seen the trunk graffiti at other plants. It makes identifying a trunk lid as Lynch Road pretty easy.

The A12 cars are very unique animals. The A12 was an option to the base Super Bee or Roadrunner. Many details on the A12 cars are left over as if it was still a 383 base model. (Tire label, fender tag, broadcast sheet and more) Please read on, I had a revelation while writing this post.

The standard tire on the 1969 Road Runner and Super Bee is an F70 x 14 RSW (T83 code). The most common marking I have for the A12 cars is either F70 X or 70 X. There is good coverage for various G70 x 15 RED markings as well which we know is the tire installed.

As I have been doing research on this topic, I have a question. When do we think this trunk label was applied in the process? Thoughts? Here is another scenario for the group to ponder. Does the F70 X or 70 X on the A12 cars mean no or eliminated? The 383 Road Runner and Super Bees I have record of wear a RED F70 designation. Just had an epiphany, the U65 code also wears a F70 X or 70 X label. Does the X mean 15 inch in place of 14 inch rims? Thoughts.....

Mike, I hope my reply answers your question on the A12 deck lids.

Darrin LOL do you remember who you are talking to?? laugh2 I can pull up copies of posts I did back in the '90's about A12 UNPAINTED FENDER TAGS and more into the mid and late 2000's and 2010-teens! Then don't forget WINGNUTS, dimpled lug nuts, and the missing late '60's - early '70's production information and............Darrin you'll have to go to bed a little later or get up a lot earlier for me to accept that as final. If what you are saying about "70 X" being a carryover from the 383 RR/SB then there should tens of thousands of "70 X" examples on other Lynch Road non-A12 383 Road Runners and Super Bees IMO. How about we check out what's on some of the 383 HP RR's and SB's. Oh and the door sticker with tire pressure on the A12's I think Chrysler got away with that and should have sent out the correct tire info to comply with in place FMVSS regulations. Getting the G70 15 tire compliance was one of the hold ups right before the start of production but that didn't stop them as they already had the open assembly line "windows" planned and filled, they were not going to hold up planned production for some silly little tire pressure label, "Labels? We don't need no stinkin Labels" laugh2 Reminds me of the Road Runner decals in 1968. Case not closed on my end grin

Funny stuff Mike, of course I remember you. Please read what I wrote again. The standard RR and SB are RED F70. Yes, there should be thousands of them out there. I am saying the X was not a sidewall designation like the R, W, and B but an indicator the tires were 15 inch. The data appears to support this across multiple tire codes.

Good to chat again by the way.

Yes, the 1969 U65 coded cars....HEMI cars. This is the data that supports the "X" is not a sidewall designation but a change in rim size. More data with markings tied to VIN or tags will help support this finding. Less than 24 hours ago I had a different view of this compared to where we are at now.

This is why I enjoy this hobby!

Would that mean the "X" might indicate 15" rim as Hemi and A12 cars had them.....................what about station wagons with 15" wheels hmmmmmmmmm? (and where the heck would they write it confused wink grin )

Very interesting thread :-)
I still don't get the intention of the marking. If the wheels were already on the car - why would a spare tire indication be necessary? I mean, if the line worker could see what rim was needed (black or color) he should be able to choose the right tire too? Maybe the correct size was a problem to spot at a glance, but the color of the stripe or RWL was so obvious... ?

what if the trunk was "loaded" before there were wheels/tires on the car work or the trunk was also the reference point for the tires on the car

Below is the paragraph from the "Patik" write up on how the Super Birds were built.

Ready sets of four tires, plus the correct spare, are dropped down metal tubes to each side of the Trim Line installation point. Assembly line boredom combined with the desire for efficiency apparently has motivated workers here to learn how to land the spare tire of each and every car with one bounce into the trunk! They will find this trick tougher on the SuperBird; its deck lid opens a limited amount, to prevent it from hitting the fastback panel.

I think we can say the tire installation at Lynch Road did not change from 1969 to 1970. This would lead me to believe the label on the trunk is a quality control check for when the tires/rims are installed on the car. It would make sense that it and other QC marks (interior on the broadcast sheet) would be applied at the beginning of the Trim Line.

Thoughts?

Is it possible that the tires and wheels were installed last, after the interior was finished and broadcast sheets all tucked away? Maybe the trunk lid tire info was written by one of last people to have access to the broadcast sheets, because the tire guys would not have a sheet to reference. I wonder if that’s why some cars built (in other plants?) have a broadcast sheet on the back of the glovebox and no trunk writing, because that sheet was used until the car was completely finished?

And even before the engine and driveline were "married". The "recipe" for assembling a car didn't change that much IMO from plant to plant, maybe the way components were delivered to those points and on which side of the assembly line some of the items may have been installed or placed (LA assembly plant jack instruction on B-bodies is typically on the left of the trunk lid versus the right side in other B-body plants for some reason?) Did the large "build" sheet that was sometimes on the front of the car on the assembly line have the wheel/tire/spare info on it?

Sounds plausible. I think we agree that it's not possible to determine what rim AND tire would be needed just from the marking, without checking another source. And if you'll have to check another source (broadcast sheet or the already installed four wheels), you don't need a marking that tells you what spare to use. So maybe it's some kind of quality control check, that the wheels and spare match the broadcast sheet.

scope Looks like there might already be a jack instruction label on the trunk lid of this Charger. I know this is the Hamtramck assembly plant but as I mentioned I'm pretty sure the recipe or procedure for Chrysler assembling vehicles during that time did not vary enough to make too many differences in the process. You can see the broadcast sheet for the interior (seat color, level) in the usual seat back and note there is no driveline, engine, etc., thus no wheels or tires. With the height of the car at this point the spare tire would be difficult to place into the trunk so was it in there already at this point or installed farther down the line. I'm starting to think that it may be an inspector's mark as noted confirming the correct spare was in place. Check out the end of the assembly line final control with trunk lid open, trunk lid closed, car being moved off the line. Was the spare and trunk inspected and a mark placed on the lid to confirm anything...................we're all just guessing wink
