. . . but if I don't replace them all won't the new pins stick out farther than the originals?
Nope, I meant that you'd trim the female end off the machine pin replacement
for the original pin, so that it would perfectly match the height of the other pins when they act as registration points.
1) cut the end pin off the short row I mail to you.
2) remove the metal pin from the plastic frame
3) trim off the female bell end of the replacement pin
4) insert modified pin into the middle of the female side of the remainder of the strip
5) plug the strip/pin assy. onto the intact pins on the appropriate row so the replacement pin fits into the hole
6) solder it into place
7) remove the "registration strip."
With any luck at all, the cylindrical portion of the machine pin will fit into the cavity for the missing pin.
If not, you'll have to chuck the pin portion of the replacement into a drill and use a jeweler's file to "Machine" it to the correct diameter . . .
. . . maybe a tad narrower than the original to leave clearance for your "solder glob."
. . . I'll send a bit longer strip than I'd intended.
