sparco globe-x shift knob - direct thread-on?
 

could anyone confirm the following scenarios for me please?

does the sparco globe-x shift knob:
1. thread directly onto the stock P5 shifter (without adapter, setting screws?)
2. thread directly onto the kartboy short shifter (without adapter, setting screws?)

does anyone have any opinions on the sparco globe-x knob -- likes/dislikes?

can anyone tell me the shifter diameter of the stock and kartboy short shifter?

thanks in advance,
dano

I have the afforementioned shift knob and it indeed has set screws. I was contemplating putting it on since I have a B&M short shifter as well but just went ahead and did it.
