Here's pic of my friends short shift. Car is actually EE80 but it's the same thing.
IIRC ball in the stick is separate. Hammer it off and reduce the diameter of the stick so that you can push the stick lover (or the ball higher on the stick). Diameter reducing can be done by lathe, file or by angle grinder. Don't take too much if using angle grinder.
Raise the whole stick assembly if needed. No need to raise that much as in the pic but my friend liked it better that way. This will only affect on longitudinal movement of the stick. Side to side movement will be the same.
