Is BSF the same as Whitworth Fine 7/8-14? (don't the Whitworth threads have a 55 degree form instead of the more normal 60 degree?)
The shortest knurl length I saw on the Alko page for 7/8 BSF is 17 mm, much longer than the thickness of the two parts of a CMP rim. But the web sites do make a starting point. At least the wheel half joining threads are all right handed.
See Tony Smith's note on the thread below - I was working from (presumed faulty) memory when I wrote the above.
