ok, from what i remember from the discussion was that the front Sportage 3rd member and the rear Miata 3rd member were the exact same unit, but i could be mistaken. also, i recall there being a discussion about what size our front R&P is- i measured it at it's widest point to be about 6-1/4 to 6-3/8" diameter, not the 7" mentioned by the solomiata guy. and as for the rear, it was rumored to be a 7.5" ring gear, and i am almost certain that is not right either. like everything else we discuss here, the only way to be sure about any of this equipment is to get it and see if it fits, period.
