Spacers to remove the sideways wobble from cheap sim handbrake.
Recommended to drill & tap (or just drill if you have long 4mm screws) holes to mount these. Most likely wont bring the needed rigidness otherwise.
I used 12x4mm screws that are perfect length if you tap threads to the original metal body.

Note! Pay attention to install orientation. The screw groove should face forward as in pics.
