Did you measure them?
the shortest magnets are 7mm overall, there has to be a 6mm magnet inside...
the longer ones are 8mm overall -> D10x7mm magnet
the 2959c01.dat is even easier to measure -> D10x7mm magnet (part is wrong)
same for 735.dat: i have a disassembled one -> D10x7mm magnet (part is wrong) (ok could have different versions)
cant check all my variants now, some parts are too well stored
for 499.dat: the outer sleeve is D11.8xL6.5mm and can fit both D10xL6mm and D10xL7mm
has another version with 7.5mm sleeve (rest is identical), fits only the D10xL7mm
