Hello folks, am I just purchased a 96x48 standard with a 4HP spindle. Assembly was very smooth until I began to mount the spindle. When I pull the z-axis beam down to expose all six mounting holes, only 4 are exposed. the other 2 are still covered by the Y-Z car which makes screwing them into the aluminum plate impossible. was I shipped the wrong car with the wrong clearance or are we just on our own to figure out how to mount this thing properly without breaking the Y-Z car. Of course with me, any help would be greatly appreciated. thank You
