I have a '69 camaro cvt. (norwood) that has a 12 bolt rear end with these codes: BL W1302.
Could someone shed some light  as why the codes are like this. Could it  be a mis-stamp?. All the letters are in a straight line.
thanks.

I split this into a new topic.
I've never seen a stamp like that. Can you get a picture of the code? That similar to a 71 stamping format, but the 12 bolt was gone by then.
What is the casting # and date from the center section? (See Decoding on this site for the locations.
Also, can you post the cowl tag and VIN for the car?

I am new to the forum and have recently purchased a 69 Camaro RS. Ironically, I have been trying to decode all of the #'s on this car and started with the rear end. One of the #'s on my rear end is BG0219G2 with an E under it. From the research I have done, if it is a posi trac it will have a letter under the sequence of #'s. The E on mine stands for Eaton. If it was a D it would stand for Dana, etc. The forst two letters I am not sure of. The next four #'s is for the date produced, ie 0219 is for Feb 19. The G is for Cevrolet Gear & Axle and the last # is for the shift. In my case it would be the 2nd shift. Check out the rear end section of the CRG website and it may help you out.

The axle is not original to the car. Looks like it is out of a 71 Nova.
I assume the casting # is actually 3969341, I don't know of a 3969340.
BL W1302 is a 71 format. I didn't realize they made a 12 bolt this year. Camaros were all 10 bolts, Novas could have a 12 bolt.
BL - 3.07  
W - Warren, MI plant
130 - 130th day of year
2 - 2nd shift
