S/S Spring question

It's a 68 dart GTS H code auto

OK.
Best I can tell, the last 3 digits of the stamped number matches the sales order/ build order code.
In other words, if we looked at a broadcast sheet the three numbers under spring will match the last three digits of one of those stamped numbers.
According to this post, one of the stamped numbers is probably a date code, and the five digit is vender code.

So you're looking for info on a 293 or 293/293
More on the codes and stamps in this one

The part numbers in the parts book are not the same, and so far I don't see a published cross reference.
Best will be to find a broadcast sheet or a photo of one.

Here's the discussion.
