Thanks Bernie, I’ve searched Google, and will keep searching.
I’ve managed to unearth a couple of 516.038 Ball Pins in my stash (see below on the right). But the rod ends are completely shot. It is those that I’ll need (or a reasonable substitute).
Meantime, I’ll try Chris and see if John Gillard can help.
