Summary

When my father passed away he left me a pile of nice wood. One of the pieces was extremely hard, and I had it made into a custom shift knob. The only problem is Subaru shift knobs have this little plastic piece on the end which attaches the boot cover to the shift knob.

If you want to DIY a shift knob, just screw this piece onto the shifter before the shift knob, and adjust so the adapter and the shift knob are next to each other.

Then drag the boot over the plastic lip, and that holds it in place.
