No shift knob with nissan thread pitch will fit my B&M shifter

[mrayburn240sx]

ok so i got a B&M short shifter from enjuku used like over a year ago anyway long story short is all B&M shifters for a 240 the same thread pitch cause i cant get any shift knob with the stock thread pitch to fit it i called b&m they said its 10mx1.25 and so did carisma. The threads arnt striped or anything either idk what to duhhh ughhh. Also my friend had a B&M shifter on his 240 and his knob would work and it was 10mx1.25 but wouldnt fit mine does anyone have any ideas?
