Naish Apex DO fit on a Shinn Monkforever.
Billy and everyone else. I have corrected your post for accuracy
As you can see they do fit a Monk Forever giving full adjustment. I hope this clears this up
The guys that got them on other shinn board are either bodging them on at a really bad angle or are cross threading their inserts and knackering the board.
Or maybe you & or the shop are tightening one side up before they put the other side in?
I can assure you I am certainly not forcing anything nor am I cross threading the screw to get it in.
It took me 5minutes to change over the pads this morning. And I am not the most patient of people
