Quoted from chuckwurt:I would be interested in this too as mine doesn't sit high enough when in the up position and causes the ball to sometime get stuck or jump off the ramp when I'm trying to lock a ball.
What I did to lift the ramp on the right side was to take the front screw out of the plate that holds the rod that lifts the ramp and put a washer underneath that which in turns lifts the ramp a little bit more.
