The pads will be about 0.4" apart, but you can get terminal posts to
fit. Wire-wrap was more common, and there will be enough clearance for
short wir-wrap posts. A common trick, though, was to clip the lead at
one end of the zero-ohm link, close to the board, and bend the zol
slightly sideways; then it can be bent back and re-made with a small
blob of solder if necessary.
