Jack Date Code??

[Sheldon S.]

I am looking at a jack that is out of a 68-76 car witha date code of 0J15, can someone tell me what this means. I thought that the date codes only have a number and letter. I ran into this once before looking at another jack. Any help greatly appreciated.
Thanks Sheldon

I have had original dated '67 and '69 jacks, and both were dated as you say, one number and one letter.

"The jack has a date code on the outer arm near the cranking end. The code is a number for the year followed by a letter for the month (eg. 9M for December 1969) All jacks have the letter "A" for Ausco stamped on the raised portion of the pad that contacts the chassis"

The jacks for 68 & 69 are different. . The 68 jack has a smaller base measuring 6by 4inches. The 69 jack is 9 by 5 inches.
All above taken form my NCRS Judging Manual for 68/69.
Hope this helps you.

Are the months assigned beginning with A for Jan, B for Feb ? If this is the case and if M is the letter for December, which letter of the alphabet is not used?

"I" was used in castings, but not in stampings.
