Here's how I've done this:
1. mark centre of rear-end of dropout where cutout
should be
2. draw 10mm circle around this spot
3. draw two straight lines going forward to connect with existing drop-out slot
4. verify drawing matches slot on left drop-out
5. drill a small 2-3mm pilot hole at spot marked in #1, make sure it's on centre
6. drill larger 10mm hole over that pilot hole
7. connect front dropout slot to rear hole with hacksaw.
8. finish off with file & paint.
