I've been told post-'67 they do still have the punch cards; or a surprising amount of them, anyway.
The problem is; there is no longer a functional system to use those punch cards in.

From what I've been told, the information on the punch cards was used to print the build sheet, among other things, probably even process the build order. . I'm sure it could collate many things.

If someone could locate the program used, build a functional system for reading the cards, and then have some new tractor-paper blank build sheets made.... there's a possibility of re-printing new build sheets.

But that's an awful lot of work.
