For those Austin Healey and Triumph owners who have struggled to replace the original pins holding the door and window winder handles in place, here is a straightforward solution: Using a suitably sized nail (it must just fit inside the handle), cut off the head, then pre-measure it to the same length as the original pin.

Cut through one third to one half of the nail's diameter. When you are ready to install the handle, insert the nail up to the cut and bend it. The nail will break off and your "shear pin" is in!

If you have difficulty seeing exactly how far to insert the nail before shearing it, tie the cut with a piece of thread, or put a drop of bright fingernail polish on it.
