Easy solution
Try some 1/8" heat shrink tubing on a small triangle file taper end. The end that tapers to almost nothing.
If you cut pieces about 1 1/4" long you will quiclkly make one just the right size to adjust the SIRS with. After you shrink about 1/2 inch onto the tip of the file, wiggle and remove the file. You will have a perfect triangular socket.
I have made these a few times for myself and others.
You can even use red heat shrink tube so they look like original equipment.
