Velocity stacks for Pioneer engines

Hi.
I'm after up to 6 velocity stacks for my Pioneer engines and am guessing they're as scarce as. If they are not available will have to make them. Does anybody know the details of material, height, diameter and amount of flare? I actually have a spare Rotax 185 with a velocity stack on it. If these are interchangeable I will have a ready made template.
Regards,
Tony

HI. Eventually found a source for Pioneer engine velocity stacks and they can be sourced from here :-

They are suitable for engines 60cc to 150cc and the screw holes are perfect fit for the Walbro carby holes.
Only US$ 6.62 aluminum or US$ 1.90 plastic.
Have attached photo of my blue aluminum one on engine.
