got a v1 wrx,sti wagon with the small rear spoilers(wrx)on the car, just bought a pair of v2 sti one's(oe subaru ones for £100) but they havent got the fittings with them(got the plastic press studs but only 1 metal threaded insert on the lower and nothing on the top one) are they the same on the small middle spoiler(wrx),also the top one appears different fitting or am i wrong.has anyone retro fitted any or can shed any light on fitting them before i start stripping it down,probably making a mountain out of a mole hill but better to double check first.thanks
mik.
