I have a 69 RS/SS that I am trying to decode. It is a 350 4 speed car but has a 10 bolt rear axle. The 1st question is didn't all SS"s have the 12 bolt?
The code on the tube is JA G043 1. I can't find anything in the codes that comes close and that's the only number on the housing. Anybody have any clues?

No, not all 1969 SS 350's came with a 12 bolt (read NOTE 9 for more info). But in your case, if the car originally came with the L48 engine and a manual transmission, it would have had a 12 bolt from the factory.

However, JA G 043 1 is a 1973 or 1974 Nova 2.73 non-posi axle, or a 1975 Nova 2.56 non-posi axle assembled the 43rd day of the year at the Detroit gear and axle plant (day shift), so it's not original to your car.

Thanks!
One turned the car upside down but haven't found a build sheet. How can I find out what rear axle code should be there?

Without paperwork there's no way to know.

What's your VIN? (post a picture of your trim tag and engine pad as well)

If it's in the database, we may have more info on the car.

The block is probably from the same donor as the rear axle.

CJD=1971 350 270hp 4 bbl. TH350 12th day of August Build.Tonawanda Engine plant N.Y. Engine was used in Chevelle, Camaro, Nova and Passenger cars.
 I'll ad that your VIN is 3661 after my 3E car, which in another post I point  out it must have left plant after the 7th of April as it has components dated April 7th.

Congrats - a real find, regardless of the engine that's in it. Tag looks like an untouched original -

How's the rest of the car ? Your header pic looks like a pretty decent Z10.

Regards (and welcome to the site),

Always good to see a new Z10 show up. Smiley
Do you know where the car came from (state or dealer)?
AC or console?

I picked up the car about 16 years ago in Cottonwood, AZ. It's an Az car as far as I know, don't know what deal ship it came from but live to know. I've not done much to it other than drive and enjoy it. It has A/C and a counsel. Has the standard interior in white. Body is straight and solid. I replaced the headliner and the 2 front bucket because of tears in the material. You all have been very informative.
Thanks!
Here are the codes from the tranny:
Case - 3925660
Tail House - 3857584
Side Cover - 388468
Stamp - P8D15, 39514, C18

It'll have to be tomorrow when the car comes back from my buddies house. Don't worry, I'm holding his '41 Hudson pickup ransom.😄

Thanks for pic. I wanted to see if it may have originally been a BB car. I am not familiar with IDing BB a/c equipped cars, which I realized your car was an a/c car right after I posted, so others may want to comment. Looks like a SB shroud and bracket though.

Not sure what you mean by BB and SB. If you need a better picture of that area  I would glad to take another now that I know what you are interested in.

Possible car could have been a factory BB= Big Block Chevrolet,IE 396 cu or SB=small block Chev. IE 350 cu. VIN has nothing to do with that. Different engine required certain components that are different between BB&SB Like engine mounts, radiator, a/c box,trans. x-member,clutch z bar,shifter,shift linkage and shift mount to trans, radiator shroud. Just because your car has a SB in it now that does not prove it originally came that way, I am trying to clarify what originally came in your car and not assuming it is a 350 car..

I can't see it clearly, but it appears to be a "L" (LOS) stamped VIN on the pad.  I've seen at least 67s with odd looking stamps - font size etc - and it may have gone on into later years as well.

It was a SS350 car originally.

Trans is from a 1968 car.

Thanks!

Case - 3925660
Tail House - 3857584
Side Cover - 388468
Stamp - P8D15, 39514, C18

Can you post a picture of the area with the P8D15 stamped code? 

And could the rest of it be CT8 39514 rather than C18?  If so, it is a 1968 replacement transmission, assembled April 15, 1968.

Next time I have it in the air I will, but that was all I could see and it was stamped in a smaller script and worn down. Not much to see.
KurtS, when you said it was an SS350 originally were you talking about my car? If so, how can you tell?

What about the AC box is different from a BB car or a non SS car?

Both halves of the engine-side box are shaped differently, and the external refirigerant plumbing and valving is different on BB cars vs. SB cars.
