What is the whole trim tag number? I think that's what's needed, maybe along with options, to determine if it is a Z. And as far as I know, production for 69's stopped at the end of Nov. 69', not December. Far be it for me to claim this as fact though, as I'm continuing to learn.

 

Look for the code (stamped numbers) on the right hand axle housing. It should have four leafs, yet the rear springs were probably changed during resto. There should be a exhaust bracket welded onto the left rear frame rail from the factory behind the shock. It is rectangular and has two holes. Do you know the build month and week stamped on the trim tag?

 

ST 69 12437 NOR102701 TR 727 7272 09C Im not much of a typer and couldnt get the trim tag to type right but this is everything thats on it Thank You

What options does the car have, be as specific as possible?

Leaf springs
Brakes
Transmission
Rearend
Factory A/C or no
etc...

Get numbers off any original drivetrain parts, I don't remember if you said if the car had original rear, trans, or engine. Can you pst any pics...especially of trimtag, vin?

09C on the trim tag would be your date code, September 3rd Week.

 

There is no date code on my trim tag. And according to my "chevy by the numbers" book.. on page 14 NOTE-There have been documented cases of trim tags that DO NOT have a month or week code. I just checked my car, no rectanguler bracket welded to frame, but there is a bracket welded to the floor pan with 2 holes and nuts welded to the back of it behind the left shock and in towards the center a little. Also I have 5 leafs, not 4!?

 

The rearend on my car may not be original. on the front of my 12 bolt are 2 sets of numbers and I cant seem to figure them out. H27B or H278? also 3894860NF or the first number could be an 8 instead of a 3. Ive read so many books regarding these cars and I find a lot of different answers from one book to another. November 69 could very well be correct, I was qouting what I had read. Thank You

 

The H278 number should be on the rear of the differential, not the front. This is the casting date, and decodes as August 27, 1968, which is correct for a September week C 1968 built car (your car). I don't know where the date "November 69" in your post comes from.
Bottom line, the rear end looks original and you need to find the application cone on the front of the right side axle tube to make an educated guess if this was an original SS or Z/28.

 

The 09C from the trim tag is the 3rd week in September. The rearend number is on the passenger side, front of the axle tube. The numbers that you found are only center section casting numbers, found on all 12 Bolts.

 

This car is Hugger Orange with Black (original?) Z28 stripes. basic interior, PS, PDB. M21 case #3851325 P0928, tailshaft casing 3857584. Its got a 350 motor cast# 3970010 that Ive chased down with a TJY suffix and the outcome didnt excite me all that much. But that will be rectified before the sun comes out next spring!!! I cant think of anything else that might help. The tilt wheel is from a 70 Nova.

 

09C is your date code - the body started build during the third week of September.

 

John, is that 3rd week Sept 68 or 69? Mine is NOR124851 which is Sept 69 isn't it? If it's that late wouldn't it be an X car?

 

The 09C # is on the bottom row of the trim tag and I believe is the acc option code which if I remember right turned out to be standard ivory interior. I was all over that rearend and I know the numbers are supposed to be on the the front pass axle tube but.....I couldnt find anything. The rear is still on the car but I was right up in there. And no A/C.

Nope. 09C is the body build date code. :thumbsup:

 

Boy did I get that mixed up 09C!!! Thanks guys

 

So, has anyone ever heard of an early production non x code 69 Z28 Camaro?

 

Every Z28 built at the Norwood assembly plant before the second week of December 1968 is a non X-code Z28. X codes didn't start to be used until then. All Los Angeles built Z28's are non X code.

 

take your back seat out and look above the x-brace, sometimes there is a code in crayon, my early 10a car has dg3 on it, standing for dark green interior x33. sometimes it starts with an x??. here's a photo

 

Take a wire brush to that axle tube. You WILL find numbers there. If you don't I would say it was retubed and it's probably from a different model car. I bet it is there though. Use a light also.

 

Also look for the numbers of the transmission when you are under there.

 

Can the transmission give you an idea if it is a SS? I have a pre x code 69 and the only thing numbers matching is the 4 speed with the entire vin stamped on it. It also has the hanger mounts, SS hood springs, and proportioning valve. Prob. not worth anymore with these very few things.

 

If the tranny is aluminum (Muncie) but the crossmember hole is oval, then it was either an SS350 or a L30/M20. (327, 250 hp, I think)[/quote]

1969 did not have an L30/M20 option, the LM1 was the continuation to the 1967 & 1968 L30/M20 option. The LM1 was only offered for about 3-4 months of the production run and offered a 350, 255hp. The LM1 used the L6 SBC crossmember used in all smallblock applications.

 

I stand corrected, if the tranny is aluminum and the crossmember has an oval access hole, it was either an LM1 or an SS350.

 

Unreal, I may be totally wrong so forgive me if I am but wouldn't a Z also have the same crossmember. According to CRG the L6 SBC crossmember was used on every smallblock application including the Z. I really don't know if there is a differnece, I'm just reading what CRG has. I guess there could have been two different crossmembers with different holes.

 

I appreciate that info, looks like I narrowed mine down to LM1 or SS350.

 

Both are pretty cool!!
