It was today's weather that reminded me how much sway there is in that fence line and that it is only a matter of time before I'll have to sort it. It then dawned on me that actually the panels are probably okay; it's the posts that are likely rotting at the base (or the concreted hole is no longer holding) and so I should replace the posts and footings sooner rather than later - that might avoid the concerns over panel matching, at least for a few more years.
