Hello. First time builder here. I searched the forums and did not see this mentioned before, I apologize if this is covered somewhere.

I just received my ES3-B4 kit and set about trying a mock build. Immediately I found the the pick ups do not fit in the routed holes lengthwise. Basically the height adjustment screws do not fit as is. Should they just drop in? If I need to expand the holes a little bit--probably just a few millimeters on each side--do I have to be super precise and have the pups perfectly centered, or is there some wiggle room.

Thank you.
