Looking For 4 Lug 114.3 To 5 Lug 114.3 Wheel Adapers

Ok so i have seen these mystic (4x114.3 - 5x114.3 1inch thick) wheel adapters before on a private sale on nico. Does anyone know were i can get a set of these? and if not how many people would want a set if i have a machine shop make them?

i would love get a set 4x114,3 to 4x100 ;-)

then i could mount my bbs wheels

theres a company that makes both of those for s13's should fit a s12 couldnt see y they wouldnt seen some on ebay too
