By any chance is the 72 connector geometry similar enough to the 41 to use a flex circuit solution? (chin rub)

The 71's connector geometry is very different from the 41. There's a picture on p.18 of this manual: http://www.hpmuseum.org/forum/attachment.php?aid=2637

The zebra is wrapped around a polymer core, then slid into the black plastic housing which has guide pins. From the pic you can see that the connector is about 0.7" long, 0.15" wide, and as I mentioned, about 0.4" high. The housing and polymer core can be salvaged, so all that's needed is a thin flex like this:
