So I bought an Olympus 28mm f/2.8 - excellent condition. Really like the output of these lenses, and after research discovered the 28mm 2.8 is a lens many struggle to adapt and mount. Leitax however, does make an adapter for this lens and can affix the Dandelion chip on it (I'm not a fan of it).
The Leitax site instructs the use of their "special" adapter when purchasing for the 28/2.8, and about 4 other pieces of OM glass, specifically.
I ordered one. It came yesterday. I converted the lens from OM to F mount. It wasn't mounting correctly. I was sad
(read: angry)
Sparing the story of how I arrived at a solution, here it is:
First, a bit of warning - the solution is somewhat destructive and you'll need to be very careful not to dirty the inside of the lens.
I didn't dirty the inside of mine, but that doesn't mean it's impossible or even unlikely; I was just fortunate. This conversion will leave some openings near the rear element and look 'naked' compared to the original lens.
If you look at Nikkor Lenses, the lens mount screws on the lens are flat-head and inset. On the Olympus 28mm f/2.8, the screws are pan-head and recessed for a fit to an Olympus body.
If you're using the original screws, you'll need to file them down to be flush on the "special" Olympus mount. If you don't, the screws will not only scratch the ever-living bejesus out of the mounting ring on the body, but it will not turn more than about 1/4".
Pictured: Unfiled screw. They don't stick up much, but it doesn't take much to impede coupling.
I used a Tamiya #400 diamond file, used to file down metal 'detail parts' when cut from a metal sprue. At the time of this writing, they're about $10.
Once the screws were flush with the mount, the lens mounts just fine and there are no issues with coupling or decoupling.
