Bob!
Hate to see this one go from you.
If it is a bit long, it is possible to remove the foot, cut or grind off a section, and then shorten (re-knot) the shock cord and reassemble.
If it is a bit short, sometimes the same Click-Stand can fit exactly if placed at another location -- say, at the intersection of seatstay and seat lug. One fits nicely under the Zefal HP on one of my rando bikes where the pump is placed horizontally under the top tube.
Even so, it might not work, and them someone will get a deal.
All the best,
Dan.
