Quoted from pinballinreno:
Ended up moving the left bracket about 5/32".
This did 2 things.
1) The playfield now pivots smoothly and cleanly, it no longer scrapes the sides.
2) the playfield no longer has to be forced onto the front hanger slots by pushing it sideways in the front.
Doing this causes the pivot to ride the left mount more rearward, raising it higher relative to the right bracket. The bracket has a slope built into it.
Pulling the playfield forward raises its height.
This caused the playfield to be higher on the left about 1/8".
The shim I added on the right is now removed.
Glad to read you fixed yours. Helpful information.
